That was INTENSE!

Man this is crazy but I thought it was going to be a turn on the tv 📺 and it works okay but man you are right it is a dam mess all over the place
It's amazing how a set that has been out in the desert for 40 years will come back to life with very little effort; but, take one that looks like it was well cared for and it's full of problems. I've experienced this sort of thing a few times.
"It looks like the termites were enjoying the select hardwood solids on this set." LOL !!!
I look at the schematics of these circuits and now, FINALLY, understand why we got a semester in the EE program that included network analysis. Loop currents, node voltages, voltage phase relationships between the nodes based on the superposition of loop currents through each component, all of which took into account the driving frequency for the reactive components . . . then the matrix math. I specialized in digital hardware design and never used any of that stuff. But now I see where it came from and where it would be used. I learned how to analyze it. I can't comprehend a mind that can synthesize such a circuit. My hats off to those engineers of yesteryear who had the gift.
Love seeing these US Round screen Colour sets. Never had these in the UK except some experimental ones built for the BBC Colour tests in the 1950s.
we in the UK had 'mass production' colour tv a bit later than the USA so sort of 'bypassed' the round colour tube era .. i've seen a pic of an ekco experimental set with round tube, but unfortunately the pic is monochrome! there may well be a colour version out there somewhere!
RCA (Radio Corporation of America) developed the color system and CRT, which was fully compatible with the existing black and white standard back in the late 1940's/early 1950's, launching their first color set to the public in 1954, which used a 15" round CRT. A year later, only 19" CRTs were used until the rectangular ones came out in the 1960's.
I worked in TV shops in the mid 1970's (in the US) and serviced both types. The round CRTs used a 70 degree deflection angle and were easier to converge. The color phosphors were much better on the round type, more pure and more accurate. The round CRTs used a shadow mask that reduced the brightness due to limiting only about 20% of the electron beam power to reach the phosphors on the screen. The round CRTs were also much more sensitive to magnetic fields than the rectangular CRTs. Also, built-in deguassers did not appear until 1965 so, CRT setup in the customer's home was quite a bit more complicated. Moving the set only a few inches, or moving a metal object in the room would affect the purity. Rotating the TV 90 degrees or moving the TV to another room would require a complete color setup from square one.
Motorola came out with the first rectangular color CRT in 1964, a 23", a 90 degree deflection type, which shortened the CRT 6". RCA followed 2 years later with a 25", which actually had the same dimensions as the Motorola. At that point, the round CRTs quickly went obsolete, with the last TV sold in 1967.
Europe was probably wise to wait a few years to "wait for the dust to settle" as the US color system had some notable problems to address.
I continue to be impressed by how much shango066 knows about these old TV sets, especially considering he was born sometime after 1970, or maybe later. I repaired TV's for a living back in the 1970's, so these roundie sets and the other stuff shango066 works on were the "meat and potatoes" of my life back then. shango066 knows more than most of the techs I worked with in the 70's! Please keep making these videos, for my aged, moderately addled brain finds them quite enjoyable!
Hearing Shango finally let loose on his disdain for the peanut gallery gave me a stiffy.
He hates the "Recap Before You Do Anything" crowd. This wasn't the first time he's gone after them, but this was definitely the most enjoyable.
I look forward to Shango066's vids on old school CRT TV sets. Watching this on a modern lcd 49"
Nice funtional design, like the ridge to prevent things from inevitabely falling behind the tv
It's called a gallery... I think. I have a Motorola B/W console that has that and the instructions on the back name it.
Hey, you can't be right all the time. Fact of the matter is, you diagnosed it using proper methods and knowledge from past experiences. We all get fooled once in a while. However, at first glance I would have fallen for the same summation = low hour and easy typical required maintenance. Great vid. 👍
I love the way the top doubles as half a tea tray.
I love theses ' ground up ' tutorials, and what better way to start than to give the re-cap crew a kicking, however a small taste of humble pie never hurt no one, I'm sure you will have this '"basket Case" sorted in no time ....cheers.
TV's from the 60s and 70's were the most fun to work on...I miss that era of servicing.
Service calls when I started in 78 were 10 bucks....most repairs were done for under $ 60.
I worked in a shop in So. Calif. and my boss liked to play golf and send me out to do his service calls (I was a bench tech there). I always fixed their sets cheap and it pissed him off that I didn't put a bunch of tubes in the set. That cured him of foisting service calls on me. He ended up dying on the golf course of a cardiac.
@@barryf5479 Ah....love that!
Eh.. $60 in 1978 is like $250 in today's dollars. Still better than just tossing it and getting a new one like most people do now though! One has to wonder just how many jobs and consumers have been screwed over by the disposable, proprietary model they use anymore.
@@FarnhamJ07 ...quite a few repair industries have fallen due to the throwaway society.!
@@FarnhamJ07 yes, people don't factor in inflation. When I tell some young guy gas was 57 cents a gallon when I started driving they freak out thinking how cheap It was, then I quickly point out the minimum wage was 2.10 cents an hour. Lol.
Me, I look forward to my Saturday morning cartoons or old TV westerns. But when Shango releases a video....all bets are on him and his fixing these sets. Gotta admit....these cliffhangers have me rooting for a successful end!
This is the same company that made the famous “Gilligan’s Island” white radio the Professor used to always mess with.
Sort of. That radio was made in Japan, I believe, so PB might have just signed the nameplate.
About that PB radio:
No such radio came like that from the factory. It received only the MW AM broadcast band.
It shows a whip antenna on the top corner - connected to nothing (that model was standard MW AM only)
The handle was added to the top of the radio - but it is the puller of a kitchen cabinet.
The real stretch: it mentions Gilligan receiving a station in Manila, during the day. Even with the superlative coverage of a signal at the bottom of the band, no place within "a three hour tour" from the Pacific coast would be in range of Manila, thousands of miles away.
@@1L6E6VHF it’s a comedy after all.
@@pcno2832
By that time, about 90% of AM transistor radios were being made in Japan, Hong Kong, or Taiwan, all bearing US brand boilerplates.
Loved the chromed kitchen cabinet handle mounted on the top of that radio.
The best line ever, “Da furst ting yu shod du is chag da kapassiters!”

I always enjoy a weekend video from Shango66's Laboratory!
Dr Shangus can fix those tvs
He might take issue with "laboratory." I think he's less formal and more of a "workshop" kind of guy.
@@johnnytacokleinschmidt515 it was a pun and joke about Mr. Carlson's Lab 😉
@@MarksKicksOnRoute66 Indeed it was! Indeed! Bwa ha ha ha. And Franlab!
@@MarksKicksOnRoute66 Glass... I can't think of his handle. Super smart guy with the earliest radios. He's cool. Makes crude vacuum tubes that work. I'm straight old hetero so I don't understand. But I'm hoping they all are happy and healthy. The console stereo collector, too. Rosie?
I might be fixing cars, trucks, air compressors, old radios, TV's, and test equipment. And speakers and stereos. Generally making a mess and not finishing anything. Playing in a band sometimes. I like the ladys. Generally rather read and play with the electronic circuits. Diagnosis and repair. I still am not very good even with all I know. Getting better though. I should be really good by about 110 years of age.
Damn Shango moving up in the world with that dim bulb tester
John McAfee is the REAL "most interesting man in the world",
He was like the Howard Hughes of the software world
He was a cool dude
@@DavenHiskey He was a hedonist who probably did off himself. Why would a 74yo hedonist want to spend the rest of his life in a US prison?
@@tarstarkusz IKR
@@tarstarkusz That's hard boiled. His body isn't even cold yet. He passed what, three days ago is all ? He was a regular James Bond being chased through south America by the CIA, and, lived on his mega yacht. Added to that he worked for Lockheed Martin, NASA, and Xerox. I agree with the O.P. he truly was the most interesting man in the world in my opinion. Who do you think they modeled the beer commercial off of ?
I'm wonderin' if those mechanical remotes are the origin of the slang term, "clicker." This term is quite common in New England.
This ones a beaut! Edit: after watching the whole video, apparently beauty is only skin deep.. Appears it may have played one too many Iron Butterfly songs..
Your videos are not a mess, they are informative and entertaining. Keep rocking Shango…you are very good ! I love your videos !
Bromeley Brometol….? Your isms, they are funny.
Tweeky tool for a 6GH8 tube ? Grrrr….6GH8 tubes are the scourge !
Had me fooled. I thought it was gonna be electronically pristine too after seeing all of the stock PB tubes and lack of dust on everything.
Wifey went to work new shango video nice packerd bell roundie by the way life dont get better than this
"We're going to the zoo, we're going to the zoo, and we're going to hong kong we're going to a lot of places yup yup"
The mocking tone with which he expressed the disdain for the "recap it" crowd reminded me of this Bill Cosby bit. Lulz.
Such a pretty set, my grandmother had an old roundie with a mechanical remote my cousin and I were not allowed to touch it lol so we did every chance we could.
When I was a really little kid in the early 70s we had a completely separate box for UHF viewing. Other than PBS for Sesame Street type programming, everything I wanted to watch was on UHF.
So did Weird Al lol
What market were you in?
@@johnnytacokleinschmidt515 Philadelphia. All of the cartoons and stuff like that were on the weekdays were on UHF, channel 48, 29 and 17. There was a New Jersey PBS station on channel 23.
PBS was 12
10 was CBS
6 was ABC and
3 was NBC (3 and 10 flipped at some point and are now the opposite (10 is NBC))
48 was WKBS Went out of business in the early 80s. Largely replaced by channel 57
29 was WTXF- though I am not sure it was called that then. It is still on the air
17 was WPHL, again, not sure it was called that then and it is also still on the air.
@@tarstarkusz That's a ton of UHF stations. We had 3 stations with our VHF only RCA B/W console. When me moved a little more central Connecticut and got a new RCA table set, B/W with allot of tubes 1975 I'm guessing we could tune channels3, 8, 30 were CBS, ABC, NBC. 24 PBS. There was a channel 18 had Doctor Scott on all of the time it seemed. I don't think we got much else. 61 FOX came in the early eighties.
Neighbors were TV shop owners. Had a satellite dish and receiver. My friend tried to show and explain it to me. I couldn't understand it at the time.
Grandparents got cable TV with the little punch button box they kept by the couch. They loved it because there were no commercials on many of the channels and they didn't have to fiddle with the antenna rotor. About $10 a month for basic...
@@tarstarkusz ps I screen shot your reply. Thanks for the information. Very interesting to me.
Amazing!! In Brazil the color TV started only in 1972, PAL-M system. My first TV set was an excelent Telefunken.
The Best... my Teatcher!!! Congratulations from Brazil!!!
Back in my old TV repair days, we used to have an 80 at 450 that we'd jump on to the electrolytics when the set was running to see if it made it work. In between jumps, we'd ground it out to discharge it so we wouldn't go over voltage on the next try. I know it's not politically correct to do that nowadays but that's what we did and it worked. We were a Zenith dealer in Whittier. I worked as a bench tech at an old appliance store back in the day. Good times.
Hello. Did you know CHARLES E STONE in La Habra / Brea area?
I'd like to thank his family for many hours he let me hang in the repair shop.
@@d.c.hammond130 No. I was in the Whittier area.
I really enjoy your channel. Your knowledge base is IMPRESSIVE. I learn a lot. I'd take up the hobby but I can't get the test equipment inexpensively.
Wow Shango I can't believe how you changed your voice. I've never heard you do that before!
Cant wait the part 2!
crusty croddydoodle action,the bane of TV repairnerds for 70 years
Ooh. I like that dim bulb tester! Simple, easy to make with parts from the hardware store.
yep filament bulbs are very useful current limiters and dummy loads, unfortunately they're getting banned even more here in europe so we need to stock up 😜
This one really has potential
The capacitor drama is amusing. I never got exposed! I am a bicycle mechanic, and we have the equivelant OCD stuff!
14:12 "May I speak to John McAfee please? Hello? John McAfee is that you?"
Wow that thing is in beautiful cosmetic condition.
1965 and tv have RC wow all the best from Romania 🇷🇴🇷🇴
When you think of all those flat screens, LCDs, there is nothing like those classic TVs with the picture tube, the new one*s once they brake, they are not worth repairing, meanwhile, you have the old TVs with the tube, you could easily fix them changing a capacitor, relay, or so
Super cool vintage tv.
Wow that TV has a pretty cabinet.
It is a nice set though, same year as I was born. The TV has aged better than I though, minus the cataract. Once the cataract is removed and you get everything else sorted out, that will produce a nice picture. The owner can then watch ME TV and vintage flintstones episodes!
Lol, im watching ME TV right now...All in the family!
The highlight of the video
11:39
DA CAPACITARRRSSS
The McAfee reference had me going pretty good there.
Great vid shango
Beautiful vintage set
Very much looking forward to the next two parts -- definitely curious to see what all is wrong with this thing. And *VERY* curious to see how you deal with that awful cataract. Thanks for making this -- I will definitely be keeping my eye out for the future vids in this series.
10:10..... Oh sure!!! We all know you turned the Beltron to rejuvenate! Now where is my warranty certificate???
Beautiful set, what's not to love
Shrink H and V size down a little and I'd leave the cataract then it would be a true roundie. With that raster image it reminded me of the Outer Limits we have control of your horizontal and vertical. Cool how the 45.xx mhz coupled through the IF tube glass capacitor. Can't wait for the next video with make picture on screen TV.
An open voltage doubler cap was the most severe problem on the TV I'm working on now. The B+ wasn't just low, it was negative!
It was negative because the set also has a B-.
Hi Shango066, another interesting set in surprisingly good condition. Just so I don't waste time troubleshooting non-problems, I would first pull the chassis, dust it off, clean the tube sockets, pots, tuner switch contacts, topped off with a visual inspection. I generally use a high voltage power supply with the current limit set very low to reform the electrolytics before applying power to the set.
I'm not sure why the half wave voltage doubler circuit was used with so many TVs that had a power transformer. Logically, I would assume they would use a 600 volt center tapped secondary for the B+ so they could just use 2 rectifiers and a single bulk filter cap. Yes, those doubler circuits pushed a huge amount of AC current through the isolated cap, and with the cardboard insulation tube over the cap body, made it run hotter and thus, shorter life.
It probably wouldn't hurt to double-check the remote unit to see if it is causing symptoms, such as muting the audio.
Optigans were made in LA, too. I've heard the Optigan guru say it's terribly hard to go more than about 90 days without a problem. Stuff isn't made with serious consideration of it being used this much later, and it is only fair to expect trouble.
Wow that's interesting, how clean and original it looked yet it really defines a "riddled" TV. I wonder if it never worked right & the virgin look to the wire dress etc was down to the attempted diagnosis by factory techs. A strange one whatever the story.
So cool!!! Reminds me of my family's old Admiral b&w set with about the same cabinet that was our TV growing up. I have photos of it if you would be willing to let me email them to you to help me identify the model.
I really like those differences between European and US TVs. The bezels around the CRTs for example. German TV sets never had them. Also those round tubes we never had. Even the first German TV; the telefunken E1 from the 1930s; had a rectangular tube without a bezel. Kinda weird.
Great video as always, btw!
like British tellys
Let zee tube bee free like die madchen! Ya! Oder nein?!
That set looks in very nice condition. We never saw Packard Bell sets in the south as I recall. I know that Curtis Mathis was in every small town here because I'd see their signs outside all the little TV shops when we drove to Florida. My parents were Zenith or RCA buyers.
We had CM dealers in the big shopping malls in the late 1970's. My uncle in NH loved his Curtis Mathis sets. I just gave him my unintentional dumb look because I thought Sylvania was the best...
Curtiss Mathis headquartered in Texas. Right? Everything in TX I'm guessing.
This is the roundie!! 1965 is a year of great 👍 TV's 📺. That looks to be vacuum tube. All ya need to fix is the capacitors, and the CRT. Once done, this should be the TV 📺 to watch ⌚ John McAfee on. It's even fan cooled!! All of our houses 🏠 should be built out of particleboard, then the termites can't eat them up ☝!! 😂😂😂. Your friend, Jeff.
+1 for the Fozzie Bear impression or whatever that was
Man all those TV's you got in the last video. So many variants you'll be forced to wear a mask in your next life.
You know, for whatever reason, I hear there are some terminally ill kids who wont be getting their wish before they die, maybe some of them would like to stop by and be entertained by Mr. FixIt and his wonderful world of TV repair!
Just don't take em to any Spa's in LA!
Hey uncle Shangus great video as always
Great video! Loved this round beauty and your rambling) You can waste my time any day.
Voltage doubler circuits tend to be hard on the filter capacitors in that circuit. I've fixed stuff for a long time and noticed that is a common problem.
Yeah, I think the doubler capacitor is pushed the hardest. Probably because it sees the highest AC current in the set. The filter cap after the doubler only sees half the current.
@@eDoc2020 we didnt use these doubler circuits much in the uk in valve/tube tvs due to the 240ish mains when direct hard rectified with a silicon diode, is about 320v , tvs very rarely had a double wound transformer to isolate from mains, but rectified it direct for ht/b+ and used series 0.3amp heaters .. any external connections such as aerial were isolated with special rated capacitors
Dan, you should get yourself some bulbs for the Beltron! lol
You can get a sound/db app, and it will “hear” the fly back (the way we use to .. could hear it with our own ears when we were young) …
Also 34:00 i thought that would be an electroboom moment
I need more shango
Change ALL the capacitors! It fixes everything they say! It even fixes bad cataracts! It's what I hear the supposed experts say despite no YT content from them.
Yes especially cataracts
ㅤ
Those tube shields are cool.
packard bell sets weren't built to last, nothing like a zenith
I use a bulb in series with a variac, it's great
best of both worlds!
For it's age it's in pretty great shape all things considered.
Was the empty hole and what looks like a dial window below the tuning knob ever addressed, what was there,, what's missing?
Shango, the first thing you need to do before plugging it in is change all the caps! It's usually good advice though, you have to admit. lol
Thanks for the tip!
Make sure to wear a condom. We don't want too may of these types.
😂😂🤣🤣🤣🤣😂😂🤣😂😂🤣👍👍🍻🍻🍻🍻 @11:40 this i why i love to watch shango. Have a good weekend 73s from PD0ROH
The rule is to expect old caps to have issues one way or another but I agree that these aluminium caps sure last long considering how old they really are now but they tend to have a high electrical leakage which can pull down voltage or damage tubes in the long run so I generally change them if I wanna use some old tech more than a few times. I am actually working on a TV myself now from the 50s or so, black and white Philips which is in absolute terrible looking shape inside compared to this and even the CRT is a bit weak but eventually I can get it work too. this old stuff dies hard but it wants lots of love and care anyway and there is not much you can find for this stuff either, I cannot even get any schematic for my TV so I will have to guess my way around with that
This is a very interesting tv.
30:58 He’s popping it! Popping it right now!
Hey...you know the first thing you should do before you turn it on is check the capacitors. Lol..sorry, couldn't resist. I'd probably end up lighting it on fire and get drunk.
7:37 sometimes fans on high voltage areas atract hairs and other debris causing arcing...often while working on a set if i blow air into the flyback with the set on there is arcing or crackling noises...have you considered that? if the dust sets naturally without wind there doesnt seem to be any arcing due to it
There is a natural circulation now as it is, the hotter it is the more air flow. But yes the fan would add more. Need periodic vacuuming, like refrigerators, that few actual do.

Nothing worthwhile was ever easy.
Nice set 👍
The new dim bulb tester tools way too safe for this channel.
Looking forward to the follow up videos on this one.
I say this was in the early 70s. Construction material and fonts seem modern.
I wish I could afford a beautiful TV like this! I hate flat screens they are so boring and crappy!
So true -
You’re right ! I just bought a Silvertone console tv from about 1957 and it produces sound, the tubes inside light up but nothing shows up on the picture tube
I trash picked an RCA CTC25 many years ago. The neck was busted off and the yokes were gone as was the power transformer. I had a similar crt that I had pulled from a solid state Zenith years before that so I put that in, got NOS yokes from Moyer, and found a large power transformer on a small chassis that took 2 5U4’s, connected it into the RCA and was able to get it to work. There is still issues but at least it seems to work for the most part. Right now we have an RCA Scenium HD monitor that is still crt. Weighs a ton but great picture.
What a shame the screen has a cataract. Hopefully that will be removed. Nice tv. I love it.
I hope I can find part 2.
I used to have a Packard Bell laptop, that had Mcaffee security on it. The thing only lasted 6 months.
Packard Bell computers had zero to do with the Packard Bell company. Some Israeli tank driver bought the rights to the name because it was well known and made PCs under that name. It has ZERO to do with Packard Bell TVs.
yeah!! shango good night! okay shango I loved seeing the Packard bell back up and running
i love your videos friend shango
i give you a tip with the multimeter try to open it and clean the coductive rubber piece thats making the connection in between the meter board and the display or try a new polarizer filter on it maybe thats gone and if theese dont work try putting more pressure on the part of the screen where the connections are i hope this helped you
Was thinking the same thing for years.
Hmm that Packard Bell in Los Angeles are they the same company that built the PB-250 computer? Yes in fact they were one and the same.
what is the boxy rectangular thing at 32:32? resistor?
I can see this one is ready to put up a fight, part 2 should be interesting. I wonder if that first IF tube is just really weak?
Can we name this teevee set John McAfee?
