Neighbors poke over the fence and see Shango in a Ninja Hood disassembling old electronics yelling at dudes with loud Cars . This is why i continue to watch ever week
@@douro20 The GDP of California is almost as big as Texas and New York combined, and it grew at the same rate as Texas last year, so I think that any death notices are probably premature.
there was another video where hes exploring abandoned stuff, maybe military bunkers and near a freeway or something and a goofey ass car drives by and he said something like oh look I took the muffler off my car to inpress my STUPID friends in classic shango form..............priceless stuff while watching these troubleshooting videos. I just wish I could find out which video it was.
well i got to say as a 20 year old... i was afraid to even touch old stuff because of the high voltages it uses to function even though i have a basic knowledge abt electronic stuff and how to work on them. but watching you did gave me the courage to fix one of my Dad's old Radios which was plagued with problems and bad caps(which to my surprise the filter caps was perfect). but yeah its now working (still has some leaky caps in the tone control circuit but idk where) and i'm just goona keep learning and keep solving the problems. Without watching your videos i would have just used "chinese tac solder wire to component method" instead of using the 2 part mechanical and solder contact you mentioned in your videos. So i would say for some ppl your videos do end up becoming educational and reviving things that were kept as a relic for 20+ years. so thankyou for making these videos and i hope it helps a lot of others to improve their skills too.
quick tack soldering is ok if just test replacing parts to see if it cures it 😉, philips didnt always bother with hooking wires round, but used small tinned copper wire 'springs', shoved the various wire ends in them and fill with solder , likely done for quickness
We all learn by doing. I started back in the mid 70's. Not what I do for a living but has always been a hobby. I have a wonderful collection of fully functional classic 5 radios. My advice for young people like yourself is don't play around with high voltage things like these old TV's until your are confident with what you're doing and have a complete understanding of the high voltage dangers. But keep it up and keep learning on old radios and stuff like that that. I can honestly say with 40 years of experience with this hobby I won't touch those old TV's because I just don't have the right tools and experience.
On your philosophical question - I think that overall videos like this provide a tremendous service to the hobby. In the future, you will not be able to own and operate a vintage piece of gear like this without some repair and service knowledge. Everyone makes mistakes when starting out. It's just that most of those mistakes end up in the landfill. I have respect for the previous 'repairer' for finding a way to get the set into hands that could repair it. The TV repair schools are gone. Apprenticeships are gone. The only way that the repair knowledge gets passed on is this.
Yeah, I think dummys gonna dumb. I know I was jumping in over my head into projects that I had no right to think I was smart enough for long before youtube. But, it's the couple that you figure out that are important!
I worked for the RCA Service Company back in the late 70's and the best thing you could get hold of is RCA's "Green Book". This was a small, (about the size of a paperback book), binder with the solutions to 95% of the problems that afflicted RCA TV's. These were issued to all RCA TV techs.
RCA Home Service Handbook AccuCircuit Color Chassis Series which first came out in 1972 with a red plastic binder. All color photos and service problems described and tells you what is the cause. The 1979 edition was a dark brown soft plastic binder and specific to Xtendedlife Unitized chassis. Bet there were more versions in between those years.
@@salvage-1electronics606 its highly unlikely such a book wouldve been 'publicly' released, but only for approved dealers/service agents, many radio/tv manufacturers wouldnt let service info out to the 'general public'
We had an earlier version of this test jig above the service bench when I worked at Montgomery Ward, plus all the adaptors to lash up just about any color chassis we brought in from the field. It too, had the words "test tube" etched into the face of the tube. Brings back alot of fond memories of those days.
Your videos are a great resource, not a disservice, sir. It’s the responsibility of the viewers to know their limitations. I use the troubleshooting skills I learn from your videos to aid in my repair of tube radios and tube stereo receivers. I know vintage TV repair is beyond my skills. I’m sure 99% of your viewers are similarly aware of their capabilities.
The vast quantity of nights I've fallen asleep listening to Shango and learning and dreaming CRTs & radios. Lovely, lovely channel for me. Thank you Shango for your efforts in sharing your work with us.
As usual Shango has great videos and he has the patience of a saint. Tango does not give up on anything he never throws in the towel he always figures it everything out. These sets will actually very reliable sets back in the day. Most of the time the service guys and the repair shop with service the sets in the house without having to pull the chassis. The only trouble that I can remember these sets giving what's the horizontal output tube would red plate and slowly burn itself out. I hope the fellow that this set belongs to appreciates your work. Me personally I would have turned it away seeing how hacked up it was.
Considering how arcane of an art vintage TV repair is now I would consider these videos a good thing. Sure you'll get overconfident idiots that torch a set or two but you'll also get people with a genuine interest that will dive in deep and actually learn the correct processes, which prolongs the life of these sets overall. Without a supply of techs there's a threat of this becoming an extinct profession.
Nichicon, Rubycon, Chemi-con, and Panasonic (all 4 are Japanese) - are the gold standard in electrolytic capacitors, they are all about equal in quality, however most Nichicon's also are solvent resistant, which is a big advantage when cleaning off flux residue and not harming the cap with solvent. Also, I should mention ELNA, a fifth premium Japanese electrolytic, but focused on high end audio. And, as you know, Digi-Key is the gold standard for the most reliable capacitor source in the world. - shango legendary quote of the day: "so for some reason, the color killer is killing the color" 😂
I agree on the recommendations. Would probably add Vishay (BC components) as well as Kemet (Rifa's part of it). ELNA however is more or less defunct since 2019 after it was acquired by Taiyo Yuden - at least no new stock is available. Audio caps was only a very small footnote in their product line up. Such a shame.
It's doing its job then, I guess. Gotta love those Shango quotes, my personal favorite, it think from the ' trip to the car wash ' video is the quote " for the sake of stupidity "
I don't really know why I watch but I'm glad that I do because it's definitely interesting and always good to learn from someone who knows what they're doing in the world.
I'm still spending a lot of my free time working on more modern sets and electronics. I spent all my life working and tearing down electronics but finding well informed videos can be harder than you think sometimes and especially on more niche "boutique" things. There's things that I never seen through experience that you have shown, so I don't think TH-cam videos are the problem. The problem is uninformed repair videos (which there's a uptick in poor content click bait videos more now). If the eager newbie decides to watch something that's missing key information they will try to fill in the blanks or learn the hard way likely failure and never finding out why. Experience is something that comes from well experience and practice. Without a guiding hand it can be extremely difficult to find your way. The home town repair shop doesn't exist anymore so the only way to pass that knowledge now is through technology or being lucky enough to just get it or have a friend that already does. Like buying questionable capacitors not everyone knows this stuff if their newer to this hell the guy running the online shop might not know the difference, wouldn't that be sad haha
A spectrum of people watch your videos. This ranges from the people who watch two videos and think they know all they need to know about TV repair, to people who know full well how to repair TV's but need information on specific chassis. But outside of repair, your videos document pieces of history that would otherwise be forgotten about. Like I never knew there was an Olympic branded TV until I saw your video on one.
Shango, your videos if anything show the importance of experience and talent since you clearly have vast amounts of both... anybody new watching one of your videos and thinking "I could do that" is probably already a lost cause. I suspect a majority of your viewers are observers of your diagnostic techniques like myself, who are in awe as each video unfolds like a narrative film.
I'm no expert and I know I'm not qualified to work on any of the tv's and radios that you do but I find your videos interesting and satisfying if someone tries to take on a project and fails I look at it as at least they tried and if there determined to get something working they will hopefully ask or get some help, these type of videos are a good thing👍👍
I am honestly in a state of shock a Trumpist who can actually read! just Wow! what a n exceedingly rare specimen Shango066 is! it's actually spelled Chango by the way your welcome!
Dear shango006, I understand how important it is to do the best job you can do, I really enjoy watching these vidoes, You are truely a professional at what you do.
*Excellent* video, I watched every second! Shango provides us with some sage advice, in which I am in complete agreement. *Never, ever* buy electronic components off of eBay -- stick to Mouser and/or Digi-Key. You'll save yourself a lot of headaches.
Yep, and not just for TV components, but just about everything of that type. For vintage items, eBay is a good resource (or can be), but it is not the ONLY source out there for vintage stuff. I see too many people prattle off "I'll just check on eBay or Amazon..." As if they are the ONLY source available when clearly, they are not. In some cases, you can get the exact same, but better parts from Mouser or Digi Key for LESS than you can for non legit copies on eBay.
eBay can be good if you need NOS or used parts - with a bit of common sense you can find reputable sellers. The new component retailers are no good if you need something like germanium transistors, for example.
Mistakes are an inevitable consequence of actually making an effort to accomplish things. It’s being willing to admit them, find a way to recover, and learn something in the process that matters. You have this part down pat. Carry on!
You know its good when 1:48 seems like 30 min , love the new piece of test gear and thank you for torturing yourself over these sets. Wonderful channel.
I'm only 6 mins in, it's been through a mincing machine. Edit: You did a great job on that. That CRT test jig looks useful. The convergence is fine as long as you wear your red/green 3D glasses. LOL.
Talk about running rich, my uncle who is rather young for an uncle is a mechanic, pretty much retired now at 85 but still in the shop to BS with customers and help out his son was a wild kid. He had a hot rod back in the 50's, all souped up with flames painted on the wheel wells, the works He took an old model T buzz coil and had it in the trunk, the set the carb to run very rich, he drill a hole in the tail pipe and inserted a spark plug, then ran a switch to the dash so he could power the coil and rev up the old Flat Head V-8, it would shoot fire out about 3 feet behind the old hot rod. We thought it was the coolest thing we ever saw back then.
Shango I always loved the approach you do towards vintage color TVs I'm looking forward to more color TV videos and how you go off on the people with anoying cars and the planes in your neighborhood it's as always entertaining
MIEC is actually a legit manufacturer of capacitors. According to their description: "MIEC specialises in the production of mid and high-voltage electrolytic capacitors. These highly reliable electrolytic are a good fit for the rigors of a long life in a power supply of valve equipment. We carry all the regular values in axial and some radial formats. Good quality, low leakage, low dissipation capacitors. Long axial tinned copper-ply leads for easy "under chassis" installation. The construction is aluminum (compact size / dry type) Polarized. Good solderability. They are rated at 600V and 105 degrees C. RoHS Compliant." They are quite expensive though... I strongly believe that your videos help a lot more than doing the harm of "sparking an interest where it shouldn't be sparked". The way to a hobby is always the same - high confidence at the beginning, a few failed projects and completely sacrificed valuable sets, than gaining experience with practice.
@@andygozzo72 Well, look again! 50uF@600V MIEC is double the size of a Nichicon 47uF@450V. I have no experience with MIEC, but they are present on sites which sell components with verified quality like hificollective and there nothings appears "by accident".
@@jassenjj theyre 'tiny' compared to original 50s/60/70s, even some 80s types of similar capacitance and voltage 😉 i think thats why a lot of 'modernish' caps seem to fail after fairly short life, compared to the older ones (i've rarely had to replace 70s and 80s made caps), too much miniaturisation,
I understand your plight! I used to work for RCA Service Co. in the 1960s and 1970s. What the owner did to this set is just a disaster!! Some basic troubleshooting would likely have revealed where the short or "pop" originated from and after determining its origin the repair for that fault probably would have been easy. Shot-gunning a chassis like this is expensive to start with and poorly done is going to result in many hours of parts and labor to correct. There are many possible faults that can cause loss of color - anywhere from poor contacts in the tuner, corroded tube pins or sockets anywhere along the signal path and into the chroma board. It turns out that many faults turn out to be due to solder around various tube sockets that has fractured due to the heating and cooling cycle of the parts over time, which results in visible stress cracks of the solder which can often be seen under good lighting while looking under the circuit board(s). Loss of ground connections to the eyelet areas where the circuit boards are soldered to the chassis was a very common fault on the chroma board. If ground is lost to a tube socket, the filament goes out and the tube no longer functions until started again cold or the board is flexed while plugging or unplugging a tube. Wires on top of the chroma board around the B+ dropping resistors (27K 3W glass types) would often char and even break loose at one end and sometimes short against nearby ground points of the circuitry. Large B+ dropping resistors underneath the HV cage were also known to develop similar problems with age and heat exposure. Wires char and corrode, terminal strip insulation can cook and degrade etc. The HV wiring you showed is a disaster and an extreme shock hazard! As you said that would have to be corrected first. If you get this one straightened out and working correctly again you definitely deserve a "Gold Star" award!!!
Oof, phew.. a sight to behold, that chassis restore. Had an all-tube Becker Mexico from a Merc sent to me recently, the owner had also restored it himself. But was dead, occasional crackle and pop. His recap was untidy, but sorta ok, a few dry joints here and there. Hours later found the fault, there were like hairs here and there, upon examination they turned out to be very fine steel wool fibres. He had cleaned up the chassis with wire brush and scouring pads. Ugh. Sabotaged his own restoration like a pro. After an extensive compressed air attack I got it going so I could align it and make the wonderbar tuning work. BTW, the fellow had also gotten his restoration tips off one or two TH-cam vids. I totally share Mr Shangos sentiments regardind the upload of vintage electronics "how to" videos, I also got a channel here in Germany and it sometimes can be very frustrating to read the comments section on how clueless people dive in into a first-time adventure with a project involving lethal voltages, fire risk etc. But of course this on the other side is offset by those who first watch countless videos by the Masters on YT like Mr.C., Shango, David Tipton, Manuel Caldeira (just to name a few) and then carefully advance forward with small projects at first, and gain valuable experience further on. These more thorough and apt "students" will be rewarded with success down the line and be the heirs to our knowledge, to hopefully pass on further along in time.. My reckoning is that one cannot stop somebody inexperienced who has their mind set upon a daunting repair, they will go ahead regardless, no way stopping them. And if they bodge up the device in the process, then so be it. I from my side will continue uploading the occasional vintage electronics tutorial as the pros seem to outweigh the cons somewhat, always good to get the occasional feedback in the comments section saying "got it going with your info" 🙂 My 2 cents, cheers from Germany
Manuel is not legit...he literally checks a circuit part by part trace by trace...he is on the hobby for so long he could should do it with real diagnostic procedure. Mister c is even worse. David tipton has amazing electronic diagnostic abilities aswell as mechanical knowledge that allows him to do incredible restorations, he has my respect and admiration. Mister c only does radios and devices that are in mint untouched condition, he doesnt film himself soldering or doing anything, he just talks, from my point of view there could be other person doing his work and we would never know...the way he spends half an hour talking about the dangers..ohhh the dangers...ohhh the lethal voltages....i just fall asleep every time...if you enjoy tvs try watching ojnoj and if you could talk portuguese there are a number of good brasilian guys fixing vintage tvs...and in germany there is meister jambo, i wish i could understand him..lool i need to learn...i already know enough to read and understand german from all the schematics and service data i went through but understanding spoken german is another story....cheers from portugal
On TH-cam videos ruining the hobby. Depends on what the viewer takes from it and their own background. You're highlighting errors and presenting an honest (if sometimes tongue-in-cheek) approach. Balancing education with entertainment. That's what I take from it. I've become an improved electronics engineer since watching you and others from all over the world, but maybe that's because I've been in the trade since 1983 and I can apply what I have seen. Newbies will have to rely on their own aptitude and gain experience through mistakes, which if we're honest we are all still doing. Shango66; There's always going to be a positive value in what you're doing. It's down to what you get from it.
Shango i always loved your videos in your way of showing how things tick.iam into vintage electronics and soild state your channel is a good learning tool in my opinion 👍💯⚛
Oh I have learned so much by watching this tv repair I wired my cousin house . And that was a new experience caught the house on fire as soon as the electric company turned it on burned the neighbors house to…. Sense then I have just done tv repair. Only burned up 4 tvs no good success yet. Still trying dude I’m learning..blew up 3:washing machines , 1 drier. 1 freezer.and 2 microwaves . . Man I am beginning to think my calling is with electricity. Been shocked go 2 times it’s a miracle I am still here. I think I better go back on welfare and let the public support me.i am not mentally ready for work I don’t think I am 60 years old never had a job so why start now. Give me my free check monthly and be happy the American way 😅😅😅
I like the existentialistic, economic and social commentaries in between the interesting technical explanations... It's the growls that I don't always understand .. especially directed at Camaro owners ;)
Great learning experience as always. I wish you could have shown us on the schematic the consequence (electrically) of not tying the binding post to ground, causing the capacitor to burst. (what the voltages went to on the different components, and what may have been damaged. That was a very interesting find. Your comment at 1:33:12 was the best !!
23:20 there's also an f&t cap, which are genuinely considered very high quality caps. Made in Germany. Used em as first filter in a couple guitar amps. Even those weren't $9, although I tend to use Mouser for cheaper, good parts.
Jigs were usually made with picture tubes with slight defects that caused them to be rejected for projection. The convergence circuit were bypassed with plug-in adapters. Nice one.
That tube mentioned around 51:45 may be branded as "Lafayette Electronics." When I was growing up in the 60's there there were Lafayette Electronic stores around including a catalog of parts they sold, etc. I believe they were based in New York and were all over the eastern portion of the US. The company went bankrupt in the eighties and were sold to Circuit City.
I remember Lafayette and they were casualty of Radio Shack. Olson's too. It was nice to have a choice, then it was Radio Shack had it or you couldn't get it. I also hated when Radio Shack had you reciting all your information to everyone in the store. I used to make sure I had all mine on a card before going there so they could just read it.
No question you can't just jump in to electronics just watching somebody. Some things maybe like spraying out contacts or cleaning tape heads or basic lubrication and upkeep. But when you get into repair and diagnosis you need to have an understanding of electronic theory and how circuits work, and work with each other. If you have common sense, and know not to put your foot under the lawnmower if there is not a sticker there to tell you, then you should know this. I been working on electronics as long as Shango and I never stop learning really. I'm glad that Shango and Radio TV Phononut and Jordan Pier and others do these videos. I know I can't hold a freakin' camera and work on this stuff. I'd electrocute myself.... LOL Cheers to you all of you! 🍻 -Al Cox
Another great Saturday morning with Shango066! A bit of triva; The "service" position for the tuner was duplicitous in its purpose. It was used in the factory in Indianapolis to put the tuner in a position for final alignment and testing prior to assembly. In the field it worked just as you say, a way to service outside the cabinet. They came up with the idea from suggestions sent in by the field service department and internal production assembly engineers. I don't know if this is true but an older radio collector that worked at RCA in Indy told me that little factoid years ago.
@@mikemiller659 The elderly man I knew said it was first for a manufacturing aid but had the service aspect in mind. Heck, it was RCA, who knew what they were thinking.
Still using those same jigs into the 90's era of Thompson Consumer Electronics/RCA. I used to sell NOS (Nasty Old Stuff) parts on Ebay. I had to stop couldn't even ship the genuine article for less than 50 pieces of junk from china delivered. BTW the term you were looking for is "rattle can restoration".
I love how you don't seem to leave your test parts in the units and make the customer purchase their own. When you have a stock of unobtainum, it's got infinite value.
When adjusting the horizontal efficiency coil, find the dip point of the current, then back the core CCW about a half turn. That compensates for the temperature increase during warm up cycle. If current is just too high even when the coil is adjusted, check the drive voltage at the grid of the horizontal output tube. If that is correct then look at the efficiency coil circuit (there are 3 capacitors near the coil on the board). One of them is a .022 if I remember correctly. You can change that to a .027 and it will allow the current in the output tube to be adjusted downward to a safer level using the efficiency coil adjustment.
JustRadios is proud to carry Axial Electrolytic Capacitors made by highly respected Miec. Miec specializes in the production of mid and high-voltage electrolytic capacitors. With over 35 years experience Miec has earned a solid reputation for producing reliable high voltage electrolytic capacitors.....
I see these videos as entertainment and preserving some knowledge of vintage electronics for future generations, not as an A-to-Z course in TV repair. I know enough electronics to follow along and enjoy, but not to take on an advanced repair job. Especially since I don't have the test equipment. My level of expertise is pulling the tubes and take them to the drug store tube tester.
Way back in the 60’s, we didn’t have Chinese junk. We had companies like “poly-paks” which sold reject parts for like 6 for $1. But they did usually hint at the definitely suspect origin of the parts.
yep in the uk many years ago there was a 'bi pak' and before that 'bi pre pak' that sold packs of stuff like that, there were other companies later doing similar packs, but almost all known good parts, as well as some 'pot luck' packs as well , i dont think any are still around now, except for one but thats changed a lot and sells mostly cctv stuff and what limited packs/parts they do have are way overpriced there was one other that had pretty much anything you could need, it was still going up to at least before the pandemic occurred, he didnt have any online presence , except an info page, no online selling, only sold directly in the shop or by good old fashioned 'mail order' or telephone !
Wow fireworks! Sounds like a war zone. Good video. I sure hope that chassis makes it back in one piece after all the trouble you went through to resurrect it.
Hey Shango... I have the same thoughts about the repair videos... I also have a channel, and I will sometime get PCBs in for a repair, that someone took a go at after watching a video or two of mine.. keep in mind I have an EE degree, and have been doing this stuff for 25 years :) anyway, I get them in all hacked up and have to work magic to get them back working.... anyway.. love the videos...
The issue is huge in auto and appliance repair. TVs are super niche. 'I saw an 11 minute youtube video on how to change the part whats wrong with my car, why do you want to charge me 4 hours?' '
When I was 15, my sister had sold this car and wanted her Clarion stereo out. Convinced me to put my Sparkomatic in there and I ran out of electrical tape fiddling around with another speaker/stereo project and had to use premade plastic address labels. Now, whoever gets the car and the dash shorts out and takes apart the wiring, they will think my father did it. One thing I always did was make a loop with the wire by twisting it around and then bending it over a few times and it makes such a strong connection, you have to rip the wire apart to get it undone.
Nice when you have pictures of the board with the traces visible. I last seen this when restoring & modifying a 40 year old base station CB radio called a ham international jumbo. It is now better than original as they clip on SSB & don't sound good on FM out of the box & in 1980 cost £224.95 that's close to £1000 in today's money. A collectors item with the front in real good shape.
Way back in my high school days, I got a part time job at a TV repair shop in Whittier. Indirectly part of one of those "ROP" (Regional Occupational Program) things. The guy that ran the shop didn't call those "alignment tools". They were (according to him), "Diddle Sticks". I watched them pull my draft lottery number on one of those test jigs (Sylvania on in our case). Mine was over 300 so I didn't have to be sent off to a swamp to die. Happy days.
Wow.. good detective work and successful microsurgery, sir. Any idea what made that winding open on that coil? Corrosion and resistance perhaps? Juat an odd failure it would seem. Also, thanks for explaining the Zenith "Solder Pot" thing. I don't have anything in my possession yet with that, but now understand how it works. Something like that coil..with multiple pots might be wise to use a hot air gun perhaps. Those greens are fricken amazing! I remember having that same model as a loaner for a few weeks when our Philco Roundie was being repaired at the shop. That Philco took a dump several times a year I swear. The repair guy was always over fixing it. 🙄
Your videos are definitely not a disservice! People have been mangling machines for as long as other people have been making them. Your knowledge and explanations at least give people a fighting chance of doing it right. Some will get it wrong, but that’s not on you. With any luck, they either give it up or try harder next time.
Many ferrite cores in transformers and coils tend to get stuck due to the heat in these chassis. If an adjustment tool encounters significant resistance to rotating the core, stop and try applying heat from a heat gun before trying again to move the core with the tool. A cracked core or broken wires as you found can definitely kill the operation of the circuit. Good find on the color oscillator AFC voltage leading to the detector diodes. The intermittent short in the 6GH8A color oscillator tube is not a common failure in that tube type, but as you discovered, it does sometimes happen. As an older tech told me years ago, the best and quickest test is to have a known good tube to try in a circuit.
Back in early 70s a neighbor had a new color set that used 6GH8 and it must have had too much load on it or something. Set worked real good except he had to get new 6GH8 every few months.
Great video! Thanks a lot! I guess you can add a convergence module to the jig. But, after all, where is my smokeless grill? I want my smokeless grill! 🤣😂
loving the vids as all ways trying my had at trying to fix pocket radios my self thing is got one and look all over the internet and cant find much on it just a few pics so stump at the moment
Question. On the TV's that had this chassis for their stereo tv combos, did the tv audio go directly to the speakers or was there a power audio amp that took the audio from both. The tv sound on those models were really good.
It's not a disservice Shango: A little perspective, face it, most of the stuff you show us is surgery on essentially obsolete and worthless electronics. That being said, the value in your vids IS the confidence to make mistakes and get better every time 'we' try. It's always the teacher, never the lesson.

I just wish I could find out which video it was.

Without watching your videos i would have just used "chinese tac solder wire to component method" instead of using the 2 part mechanical and solder contact you mentioned in your videos.
So i would say for some ppl your videos do end up becoming educational and reviving things that were kept as a relic for 20+ years. so thankyou for making these videos and i hope it helps a lot of others to improve their skills too.
quick tack soldering is ok if just test replacing parts to see if it cures it 😉, philips didnt always bother with hooking wires round, but used small tinned copper wire 'springs', shoved the various wire ends in them and fill with solder , likely done for quickness
We all learn by doing. I started back in the mid 70's. Not what I do for a living but has always been a hobby. I have a wonderful collection of fully functional classic 5 radios. My advice for young people like yourself is don't play around with high voltage things like these old TV's until your are confident with what you're doing and have a complete understanding of the high voltage dangers. But keep it up and keep learning on old radios and stuff like that that. I can honestly say with 40 years of experience with this hobby I won't touch those old TV's because I just don't have the right tools and experience.
On your philosophical question - I think that overall videos like this provide a tremendous service to the hobby. In the future, you will not be able to own and operate a vintage piece of gear like this without some repair and service knowledge. Everyone makes mistakes when starting out. It's just that most of those mistakes end up in the landfill. I have respect for the previous 'repairer' for finding a way to get the set into hands that could repair it. The TV repair schools are gone. Apprenticeships are gone. The only way that the repair knowledge gets passed on is this.
Yeah, I think dummys gonna dumb. I know I was jumping in over my head into projects that I had no right to think I was smart enough for long before youtube. But, it's the couple that you figure out that are important!

I worked for the RCA Service Company back in the late 70's and the best thing you could get hold of is RCA's "Green Book". This was a small, (about the size of a paperback book), binder with the solutions to 95% of the problems that afflicted RCA TV's. These were issued to all RCA TV techs.
ohh message me the details please, i want!
RCA Home Service Handbook AccuCircuit Color Chassis Series which first came out in 1972 with a red plastic
binder. All color photos and service problems described and tells you what is the cause. The 1979 edition was
a dark brown soft plastic binder and specific to Xtendedlife Unitized chassis. Bet there were more versions in
between those years.
@@shango066 I have searched on Google & Ebay and I can find no mention of this book anywhere :-(
@Frank's Vintage Audio and TV I have searched everywhere & I can find no mention of this book 😞
@@salvage-1electronics606 its highly unlikely such a book wouldve been 'publicly' released, but only for approved dealers/service agents, many radio/tv manufacturers wouldnt let service info out to the 'general public'
We had an earlier version of this test jig above the service bench when I worked at Montgomery Ward, plus all the adaptors to lash up just about any color chassis we brought in from the field. It too, had the words "test tube" etched into the face of the tube.
Brings back alot of fond memories of those days.
Your videos are a great resource, not a disservice, sir. It’s the responsibility of the viewers to know their limitations. I use the troubleshooting skills I learn from your videos to aid in my repair of tube radios and tube stereo receivers. I know vintage TV repair is beyond my skills. I’m sure 99% of your viewers are similarly aware of their capabilities.
The vast quantity of nights I've fallen asleep listening to Shango and learning and dreaming CRTs & radios. Lovely, lovely channel for me. Thank you Shango for your efforts in sharing your work with us.
With the success you achieved, I now award you a "Gold Star". You definitely deserve it!!!
1:30:04 She is a very cute and nice kitty! Thanks for feeding her Shango. All of our cats are strays that adopted us.
As usual Shango has great videos and he has the patience of a saint. Tango does not give up on anything he never throws in the towel he always figures it everything out. These sets will actually very reliable sets back in the day. Most of the time the service guys and the repair shop with service the sets in the house without having to pull the chassis. The only trouble that I can remember these sets giving what's the horizontal output tube would red plate and slowly burn itself out. I hope the fellow that this set belongs to appreciates your work. Me personally I would have turned it away seeing how hacked up it was.
Thanks for taking us through the diagnosis of the diodes. I really enjoy the long form video format.
Considering how arcane of an art vintage TV repair is now I would consider these videos a good thing. Sure you'll get overconfident idiots that torch a set or two but you'll also get people with a genuine interest that will dive in deep and actually learn the correct processes, which prolongs the life of these sets overall. Without a supply of techs there's a threat of this becoming an extinct profession.
Just hearing an expert declare their parts sources is golden to me. Thanks.
I really respect how you didn't edit out your mistake. We all make em.
Nichicon, Rubycon, Chemi-con, and Panasonic (all 4 are Japanese) - are the gold standard in electrolytic capacitors, they are all about equal in quality, however most Nichicon's also are solvent resistant, which is a big advantage when cleaning off flux residue and not harming the cap with solvent. Also, I should mention ELNA, a fifth premium Japanese electrolytic, but focused on high end audio. And, as you know, Digi-Key is the gold standard for the most reliable capacitor source in the world. - shango legendary quote of the day: "so for some reason, the color killer is killing the color" 😂
I agree on the recommendations. Would probably add Vishay (BC components) as well as Kemet (Rifa's part of it). ELNA however is more or less defunct since 2019 after it was acquired by Taiyo Yuden - at least no new stock is available. Audio caps was only a very small footnote in their product line up. Such a shame.
Thats what the color killer does it appears haha..
For more bucks I prefer DC link caps. Last forever.
One of my favorites has to be:
"We're going to measure between the DO NOT MEASURE line and ground."
It's doing its job then, I guess.
Gotta love those Shango quotes, my personal favorite, it think from the
' trip to the car wash ' video is the quote
" for the sake of stupidity "
I don't really know why I watch but I'm glad that I do because it's definitely interesting and always good to learn from someone who knows what they're doing in the world.
I'm still spending a lot of my free time working on more modern sets and electronics. I spent all my life working and tearing down electronics but finding well informed videos can be harder than you think sometimes and especially on more niche "boutique" things.
There's things that I never seen through experience that you have shown, so I don't think TH-cam videos are the problem. The problem is uninformed repair videos (which there's a uptick in poor content click bait videos more now). If the eager newbie decides to watch something that's missing key information they will try to fill in the blanks or learn the hard way likely failure and never finding out why.
Experience is something that comes from well experience and practice. Without a guiding hand it can be extremely difficult to find your way. The home town repair shop doesn't exist anymore so the only way to pass that knowledge now is through technology or being lucky enough to just get it or have a friend that already does. Like buying questionable capacitors not everyone knows this stuff if their newer to this hell the guy running the online shop might not know the difference, wouldn't that be sad haha
A spectrum of people watch your videos. This ranges from the people who watch two videos and think they know all they need to know about TV repair, to people who know full well how to repair TV's but need information on specific chassis.
But outside of repair, your videos document pieces of history that would otherwise be forgotten about. Like I never knew there was an Olympic branded TV until I saw your video on one.
Shango, your videos if anything show the importance of experience and talent since you clearly have vast amounts of both... anybody new watching one of your videos and thinking "I could do that" is probably already a lost cause. I suspect a majority of your viewers are observers of your diagnostic techniques like myself, who are in awe as each video unfolds like a narrative film.
The wires wrapped around the shoe buffer was the hardest I have laughed in a long time
I laughed because why didn't he simply use an acid brush and alcohol? Shoe buffer? That'll work!
I would have paid to have see a video of the "wrapping".
I'm no expert and I know I'm not qualified to work on any of the tv's and radios that you do but I find your videos interesting and satisfying if someone tries to take on a project and fails I look at it as at least they tried and if there determined to get something working they will hopefully ask or get some help, these type of videos are a good thing👍👍
this kind of yt videos keep alive some hobbies not otherwise
I am honestly in a state of shock a Trumpist who can actually read! just Wow! what a n exceedingly rare specimen Shango066 is! it's actually spelled Chango by the way your welcome!
Dear shango006, I understand how important it is to do the best job you can do, I really enjoy watching these vidoes, You are truely a professional at what you do.
*Excellent* video, I watched every second! Shango provides us with some sage advice, in which I am in complete agreement. *Never, ever* buy electronic components off of eBay -- stick to Mouser and/or Digi-Key. You'll save yourself a lot of headaches.
Agree 100 percent.
Been there, done that, fake shite, more headaches, more destruction. Buy the real stuff.
Yep, and not just for TV components, but just about everything of that type. For vintage items, eBay is a good resource (or can be), but it is not the ONLY source out there for vintage stuff. I see too many people prattle off "I'll just check on eBay or Amazon..." As if they are the ONLY source available when clearly, they are not. In some cases, you can get the exact same, but better parts from Mouser or Digi Key for LESS than you can for non legit copies on eBay.
I don't typically buy components off of eBay unless they're NOS lots.
eBay can be good if you need NOS or used parts - with a bit of common sense you can find reputable sellers. The new component retailers are no good if you need something like germanium transistors, for example.
Mistakes are an inevitable consequence of actually making an effort to accomplish things. It’s being willing to admit them, find a way to recover, and learn something in the process that matters. You have this part down pat. Carry on!
Full blown facial cover up, really like the hoodie. Full camo too. You rock my world Shango !! 😃
Reminded me of the Invisible Man with Ray Milland.
You know its good when 1:48 seems like 30 min , love the new piece of test gear and thank you for torturing yourself over these sets. Wonderful channel.
I'm only 6 mins in, it's been through a mincing machine.
Edit: You did a great job on that.
That CRT test jig looks useful.
The convergence is fine as long as you wear your red/green 3D glasses. LOL.
Long and comprehensive video. Nice.
What a job. Must have taken lots of hours.
Thank you 👍
Talk about running rich, my uncle who is rather young for an uncle is a mechanic, pretty much retired now at 85 but still in the shop to BS with customers and help out his son was a wild kid. He had a hot rod back in the 50's, all souped up with flames painted on the wheel wells, the works He took an old model T buzz coil and had it in the trunk, the set the carb to run very rich, he drill a hole in the tail pipe and inserted a spark plug, then ran a switch to the dash so he could power the coil and rev up the old Flat Head V-8, it would shoot fire out about 3 feet behind the old hot rod. We thought it was the coolest thing we ever saw back then.
NO, You are giving old vintage electronics a wonderful service. I think the finest we have.
I watch these videos as a self-aware no-talent watching an artist at work, appreciating the craft.
I’m always amazed by your massive depth of knowledge. Lovely in-depth video
Shango I always loved the approach you do towards vintage color TVs I'm looking forward to more color TV videos and how you go off on the people with anoying cars and the planes in your neighborhood it's as always entertaining
Shango001 for President? Hell yea! You got my vote and thousands more! Thanks for posting and take care!
MIEC is actually a legit manufacturer of capacitors. According to their description:
"MIEC specialises in the production of mid and high-voltage electrolytic capacitors. These highly reliable electrolytic are a good fit for the rigors of a long life in a power supply of valve equipment. We carry all the regular values in axial and some radial formats. Good quality, low leakage, low dissipation capacitors. Long axial tinned copper-ply leads for easy "under chassis" installation. The construction is aluminum (compact size / dry type) Polarized. Good solderability. They are rated at 600V and 105 degrees C. RoHS Compliant."
They are quite expensive though...
I strongly believe that your videos help a lot more than doing the harm of "sparking an interest where it shouldn't be sparked". The way to a hobby is always the same - high confidence at the beginning, a few failed projects and completely sacrificed valuable sets, than gaining experience with practice.
they do look a bit 'small' for what they are, though, i'd wonder about ripple capability,
@@andygozzo72 Well, look again! 50uF@600V MIEC is double the size of a Nichicon 47uF@450V.
I have no experience with MIEC, but they are present on sites which sell components with verified quality like hificollective and there nothings appears "by accident".
@@jassenjj theyre 'tiny' compared to original 50s/60/70s, even some 80s types of similar capacitance and voltage 😉 i think thats why a lot of 'modernish' caps seem to fail after fairly short life, compared to the older ones (i've rarely had to replace 70s and 80s made caps), too much miniaturisation,
@6:34 - shango066 is beyond words. The master orator is speechless.
I see we're riding the short bus together today! Thanks for letting the mistakes in, makes me feel better about mine
I understand your plight! I used to work for RCA Service Co. in the 1960s and 1970s. What the owner did to this set is just a disaster!! Some basic troubleshooting would likely have revealed where the short or "pop" originated from and after determining its origin the repair for that fault probably would have been easy. Shot-gunning a chassis like this is expensive to start with and poorly done is going to result in many hours of parts and labor to correct. There are many possible faults that can cause loss of color - anywhere from poor contacts in the tuner, corroded tube pins or sockets anywhere along the signal path and into the chroma board. It turns out that many faults turn out to be due to solder around various tube sockets that has fractured due to the heating and cooling cycle of the parts over time, which results in visible stress cracks of the solder which can often be seen under good lighting while looking under the circuit board(s). Loss of ground connections to the eyelet areas where the circuit boards are soldered to the chassis was a very common fault on the chroma board. If ground is lost to a tube socket, the filament goes out and the tube no longer functions until started again cold or the board is flexed while plugging or unplugging a tube. Wires on top of the chroma board around the B+ dropping resistors (27K 3W glass types) would often char and even break loose at one end and sometimes short against nearby ground points of the circuitry. Large B+ dropping resistors underneath the HV cage were also known to develop similar problems with age and heat exposure. Wires char and corrode, terminal strip insulation can cook and degrade etc. The HV wiring you showed is a disaster and an extreme shock hazard! As you said that would have to be corrected first. If you get this one straightened out and working correctly again you definitely deserve a "Gold Star" award!!!
@1:01:03 - This mea culpa is part of the reason why I enjoy your content so much. There is no editing or bullshit. We get it raw.
Been watching these videos for some time now and I guess I'm not at all shocked to find that shango is a Jawa.
Oof, phew.. a sight to behold, that chassis restore. Had an all-tube Becker Mexico from a Merc sent to me recently, the owner had also restored it himself. But was dead, occasional crackle and pop. His recap was untidy, but sorta ok, a few dry joints here and there. Hours later found the fault, there were like hairs here and there, upon examination they turned out to be very fine steel wool fibres. He had cleaned up the chassis with wire brush and scouring pads. Ugh. Sabotaged his own restoration like a pro.
After an extensive compressed air attack I got it going so I could align it and make the wonderbar tuning work. BTW, the fellow had also gotten his restoration tips off one or two TH-cam vids.
I totally share Mr Shangos sentiments regardind the upload of vintage electronics "how to" videos, I also got a channel here in Germany and it sometimes can be very frustrating to read the comments section on how clueless people dive in into a first-time adventure with a project involving lethal voltages, fire risk etc.
But of course this on the other side is offset by those who first watch countless videos by the Masters on YT like Mr.C., Shango, David Tipton, Manuel Caldeira (just to name a few) and then carefully advance forward with small projects at first, and gain valuable experience further on. These more thorough and apt "students" will be rewarded with success down the line and be the heirs to our knowledge, to hopefully pass on further along in time..
My reckoning is that one cannot stop somebody inexperienced who has their mind set upon a daunting repair, they will go ahead regardless, no way stopping them. And if they bodge up the device in the process, then so be it.
I from my side will continue uploading the occasional vintage electronics tutorial as the pros seem to outweigh the cons somewhat, always good to get the occasional feedback in the comments section saying "got it going with your info" 🙂
My 2 cents, cheers from Germany
Manuel is not legit...he literally checks a circuit part by part trace by trace...he is on the hobby for so long he could should do it with real diagnostic procedure. Mister c is even worse. David tipton has amazing electronic diagnostic abilities aswell as mechanical knowledge that allows him to do incredible restorations, he has my respect and admiration. Mister c only does radios and devices that are in mint untouched condition, he doesnt film himself soldering or doing anything, he just talks, from my point of view there could be other person doing his work and we would never know...the way he spends half an hour talking about the dangers..ohhh the dangers...ohhh the lethal voltages....i just fall asleep every time...if you enjoy tvs try watching ojnoj and if you could talk portuguese there are a number of good brasilian guys fixing vintage tvs...and in germany there is meister jambo, i wish i could understand him..lool i need to learn...i already know enough to read and understand german from all the schematics and service data i went through but understanding spoken german is another story....cheers from portugal
Wow! I can understand what you feel! Once I faced similar nightmare after kind of " Tried to fix and ruined everything".
Looks like our bot is MIA this week. Nice fix, I watched to the end...like I do every week
On TH-cam videos ruining the hobby. Depends on what the viewer takes from it and their own background. You're highlighting errors and presenting an honest (if sometimes tongue-in-cheek) approach. Balancing education with entertainment. That's what I take from it. I've become an improved electronics engineer since watching you and others from all over the world, but maybe that's because I've been in the trade since 1983 and I can apply what I have seen. Newbies will have to rely on their own aptitude and gain experience through mistakes, which if we're honest we are all still doing. Shango66; There's always going to be a positive value in what you're doing. It's down to what you get from it.
omg what a battle but Shango got it did 😵💫, Well done mate. Paul from the UK
Shango i always loved your videos in your way of showing how things tick.iam into vintage electronics and soild state your channel is a good learning tool in my opinion 👍💯⚛
surreal~ respect for glowing tubes~!
Oh I have learned so much by watching this tv repair I wired my cousin house . And that was a new experience caught the house on fire as soon as the electric company turned it on burned the neighbors house to…. Sense then I have just done tv repair. Only burned up 4 tvs no good success yet. Still trying dude I’m learning..blew up 3:washing machines , 1 drier. 1 freezer.and 2 microwaves . . Man I am beginning to think my calling is with electricity. Been shocked go 2 times it’s a miracle I am still here. I think I better go back on welfare and let the public support me.i am not mentally ready for work I don’t think I am 60 years old never had a job so why start now. Give me my free check monthly and be happy the American way 😅😅😅
6.5 minutes in, I was like "Pull the tubes out of that chassis and throw the rest of that mess in the trash", but in true Shango fashion, it works!
I like the existentialistic, economic and social commentaries in between the interesting technical explanations... It's the growls that I don't always understand .. especially directed at Camaro owners ;)
meat by products.....IN COLOR TOOO!!!! i COULD binge watch all the videos for a week!
Great learning experience as always. I wish you could have shown us on the schematic the consequence (electrically) of not tying the binding post to ground, causing the capacitor to burst. (what the voltages went to on the different components, and what may have been damaged. That was a very interesting find.
Your comment at 1:33:12 was the best !!
I have to add... I share your exact thoughts at 1:36:58
23:20 there's also an f&t cap, which are genuinely considered very high quality caps. Made in Germany. Used em as first filter in a couple guitar amps. Even those weren't $9, although I tend to use Mouser for cheaper, good parts.
We all enjoy your sense of humor, and perhaps there's hope for California yet.🤠😁
And for such films I subscribe this channel. Almost 2 hours with Shango066? Of course and thank you. Would it be longer? Even better.
The best thing was in the beginning, when lifting that layer of tacked on components on long leads - maybe I'll just give him another chassis :)
I'm all in on a "More Shango066" channel without edits, similar to the "More Kitboga " channel. 5-6 hour full repairs plus commentary? Sign me up!
Jigs were usually made with picture tubes with slight defects that caused them to be rejected for projection. The convergence circuit were bypassed with plug-in adapters. Nice one.
That tube mentioned around 51:45 may be branded as "Lafayette Electronics." When I was growing up in the 60's there there were Lafayette Electronic stores around including a catalog of parts they sold, etc. I believe they were based in New York and were all over the eastern portion of the US. The company went bankrupt in the eighties and were sold to Circuit City.
I remember Lafayette and they were casualty of Radio Shack.
Olson's too. It was nice to have a choice, then it was Radio Shack had it or you couldn't get it.
I also hated when Radio Shack had you reciting all your information to everyone in the store. I used to make sure I had all mine on a card before going there so they could just read it.
I love it! Shango getting grumpier with each new video! Hilarious!
No question you can't just jump in to electronics just watching
somebody. Some things maybe like spraying out contacts or
cleaning tape heads or basic lubrication and upkeep. But when
you get into repair and diagnosis you need to have an understanding
of electronic theory and how circuits work, and work with each
other. If you have common sense, and know not to put your foot
under the lawnmower if there is not a sticker there to tell you, then
you should know this. I been working on electronics as long as
Shango and I never stop learning really. I'm glad that Shango and
Radio TV Phononut and Jordan Pier and others do these videos.
I know I can't hold a freakin' camera and work on this stuff.
I'd electrocute myself.... LOL Cheers to you all of you! 🍻 -Al Cox
Thanks for another great vid. You'er head wrap game is strong!!!
Thanks!
Another great Saturday morning with Shango066! A bit of triva; The "service" position for the tuner was duplicitous in its purpose. It was used in the factory in Indianapolis to put the tuner in a position for final alignment and testing prior to assembly. In the field it worked just as you say, a way to service outside the cabinet. They came up with the idea from suggestions sent in by the field service department and internal production assembly engineers. I don't know if this is true but an older radio collector that worked at RCA in Indy told me that little factoid years ago.
duplicitous ?
@@mikemiller659 The elderly man I knew said it was first for a manufacturing aid but had the service aspect in mind. Heck, it was RCA, who knew what they were thinking.
I agree one hundred percent. It is essential for assembly. Nice that feature can be used later in it's life.
I would dare say quite duplicitous.
That's 13:30 That repair technique is called the "Tijuana Tack and Tape."
Wow the chassis overview at the start there.... Wow. Just what in the heck
Still using those same jigs into the 90's era of Thompson Consumer Electronics/RCA.
I used to sell NOS (Nasty Old Stuff) parts on Ebay. I had to stop couldn't even ship the genuine article for less than 50 pieces of junk from china delivered.
BTW the term you were looking for is "rattle can restoration".
I love how you don't seem to leave your test parts in the units and make the customer purchase their own. When you have a stock of unobtainum, it's got infinite value.
OMG..... JUST 2 minutes into seeing the chassis underside and I can only express: "GOLLY!"
When adjusting the horizontal efficiency coil, find the dip point of the current, then back the core CCW about a half turn. That compensates for the temperature increase during warm up cycle. If current is just too high even when the coil is adjusted, check the drive voltage at the grid of the horizontal output tube. If that is correct then look at the efficiency coil circuit (there are 3 capacitors near the coil on the board). One of them is a .022 if I remember correctly. You can change that to a .027 and it will allow the current in the output tube to be adjusted downward to a safer level using the efficiency coil adjustment.
JustRadios is proud to carry Axial Electrolytic Capacitors made by highly respected Miec. Miec specializes in the production of mid and high-voltage electrolytic capacitors. With over 35 years experience Miec has earned a solid reputation for producing reliable high voltage electrolytic capacitors.....
Shango066, your commentary is 'THE BEST'! LOL!
Great Job and video on of your best. Love to watch every Saturday you make my day. Learn something on each video you're the best on T.Vs
Mate I enjoyed this video, top quality stuff.
I see these videos as entertainment and preserving some knowledge of vintage electronics for future generations, not as an A-to-Z course in TV repair. I know enough electronics to follow along and enjoy, but not to take on an advanced repair job. Especially since I don't have the test equipment. My level of expertise is pulling the tubes and take them to the drug store tube tester.
Way back in the 60’s, we didn’t have Chinese junk. We had companies like “poly-paks” which sold reject parts for like 6 for $1. But they did usually hint at the definitely suspect origin of the parts.
yep in the uk many years ago there was a 'bi pak' and before that 'bi pre pak' that sold packs of stuff like that, there were other companies later doing similar packs, but almost all known good parts, as well as some 'pot luck' packs as well , i dont think any are still around now, except for one but thats changed a lot and sells mostly cctv stuff and what limited packs/parts they do have are way overpriced there was one other that had pretty much anything you could need, it was still going up to at least before the pandemic occurred, he didnt have any online presence , except an info page, no online selling, only sold directly in the shop or by good old fashioned 'mail order' or telephone !
I've seen "brave" people messing around with old electronics looooooong before the TH-cam existed. With catastrofic results of course.
Wow fireworks! Sounds like a war zone. Good video. I sure hope that chassis makes it back in one piece after all the trouble you went through to resurrect it.
am transfixed by your efforts~
Love the little kitty cat, Shango!
Hey Shango... I have the same thoughts about the repair videos... I also have a channel, and I will sometime get PCBs in for a repair, that someone took a go at after watching a video or two of mine.. keep in mind I have an EE degree, and have been doing this stuff for 25 years :) anyway, I get them in all hacked up and have to work magic to get them back working.... anyway.. love the videos...
The issue is huge in auto and appliance repair. TVs are super niche. 'I saw an 11 minute youtube video on how to change the part whats wrong with my car, why do you want to charge me 4 hours?'
'
When I was 15, my sister had sold this car and wanted her Clarion stereo out. Convinced me to put my Sparkomatic in there and I ran out of electrical tape fiddling around with another speaker/stereo project and had to use premade plastic address labels. Now, whoever gets the car and the dash shorts out and takes apart the wiring, they will think my father did it. One thing I always did was make a loop with the wire by twisting it around and then bending it over a few times and it makes such a strong connection, you have to rip the wire apart to get it undone.
Nice when you have pictures of the board with the traces visible. I last seen this when restoring & modifying a 40 year old base station CB radio called a ham international jumbo. It is now better than original as they clip on SSB & don't sound good on FM out of the box & in 1980 cost £224.95 that's close to £1000 in today's money. A collectors item with the front in real good shape.
Way back in my high school days, I got a part time job at a TV repair shop in Whittier. Indirectly part of one of those "ROP" (Regional Occupational Program) things. The guy that ran the shop didn't call those "alignment tools". They were (according to him), "Diddle Sticks".
I watched them pull my draft lottery number on one of those test jigs (Sylvania on in our case). Mine was over 300 so I didn't have to be sent off to a swamp to die. Happy days.
Wow.. good detective work and successful microsurgery, sir. Any idea what made that winding open on that coil? Corrosion and resistance perhaps? Juat an odd failure it would seem. Also, thanks for explaining the Zenith "Solder Pot" thing. I don't have anything in my possession yet with that, but now understand how it works. Something like that coil..with multiple pots might be wise to use a hot air gun perhaps. Those greens are fricken amazing! I remember having that same model as a loaner for a few weeks when our Philco Roundie was being repaired at the shop. That Philco took a dump several times a year I swear. The repair guy was always over fixing it. 🙄
26:46 why are there 4 holes on the side of those resistors ? I’ve always been wondering 😳😳
@1:29:35 ish... do i see an arc bottom middle by big blue resistor?

Your videos are definitely not a disservice! People have been mangling machines for as long as other people have been making them. Your knowledge and explanations at least give people a fighting chance of doing it right.
Some will get it wrong, but that’s not on you. With any luck, they either give it up or try harder next time.
ooooh - a long shango video 👍🏻👍🏻👍🏻👍🏻
I discovered some carbon tracking in an early 60's Zenith record player that I am working on. It was carbon tracking on a tube socket.
Many ferrite cores in transformers and coils tend to get stuck due to the heat in these chassis. If an adjustment tool encounters significant resistance to rotating the core, stop and try applying heat from a heat gun before trying again to move the core with the tool. A cracked core or broken wires as you found can definitely kill the operation of the circuit. Good find on the color oscillator AFC voltage leading to the detector diodes. The intermittent short in the 6GH8A color oscillator tube is not a common failure in that tube type, but as you discovered, it does sometimes happen. As an older tech told me years ago, the best and quickest test is to have a known good tube to try in a circuit.
Back in early 70s a neighbor had a new color set that used 6GH8 and it must have had too much load on it or something. Set worked real good except he had to get new 6GH8 every few months.
Great video! Thanks a lot! I guess you can add a convergence module to the jig. But, after all, where is my smokeless grill? I want my smokeless grill! 🤣😂
loving the vids as all ways trying my had at trying to fix pocket radios my self thing is got one and look all over the internet and cant find much on it just a few pics so stump at the moment
Great stuff. You cracked me up at 1:44:30
Question. On the TV's that had this chassis for their stereo tv combos, did the tv audio go directly to the speakers or was there a power audio amp that took the audio from both. The tv sound on those models were really good.
It's not a disservice Shango: A little perspective, face it, most of the stuff you show us is surgery on essentially obsolete and worthless electronics. That being said, the value in your vids IS the confidence to make mistakes and get better every time 'we' try. It's always the teacher, never the lesson.
