someday build a regen from own design... or off net. would be cool.. wu2d used one of them new flat tubes or something . but be cool see what you would come up with .
@@XPFTP Interesting. That would be 1 kick ass radio if Mr. C built it from the bottom up.
Do you have any idea while old Tek scopes with 50+ tubes can still be working but many TV with tubes had them frequently go out? Did Tek use higher quality tubes?
Please do the restoration. It is one of the few valve/tube radios that is not older than l am!
TVs generally are very hard on certain tubes due to circuit demands. Think HV, damper, etc, that run near design limits while ‘as the world ends’ and ‘the young and the useless’ run the raster all day long;)
This is a perfect example of 60’s design. Maybe that is why it deserves to survive. I would say yes.
I agree. This little radio is an example of technology in transition. I graduated HS in 1962. I was just getting to really understand tubes when we blown up by the humble CK722 transistor. What are holes?
*Word.*
It's one of those where technology is in transition. It's probably a rare survivor of its model.
So, I think that it deserves to be properly restored rather than being a spares donor.
I've been telling my psychiatrist the same thing about myself.
@@icanfartloud 🤣
This little unit deserves a full restoration, with maybe a full range speaker.
Your one of the best instructors on TH-cam, Sir!
for sure I have Viston brand speakers that I use as a replacement when needed !
I do not think that radio deserves life. So much cost cutting b.s. So much heat into that circuit board. Yuck. But kudos to you for fooling with it.
How much would an old radio like this pull(Watts) from the wall ?
@@drupiROMThe tubes alone should pull something like 25W.
Yes to restoration Mr Carlson! You have gone this far with this radio, so a complete restoration is my vote!
It would be cool to see this get the official Mr. Carlson tune-up (TM)! The main interest would be to see how well such a modest radio could perform if it was given a proper full electrical restore. It might also be interesting to compare it to one of the "grand" tuners to see how deaf it is comparatively once fixed up.
Yes! AND could he enhance it if it was lacking in some way. One of his little circuit boards? I am sure he could do that.
*lol* at Scott!!! I dig the *TM* - - - - good job, thanks for making me smile. :o)
I would like to see the restoration and tuning. I have several Zenith AM/FM tube receivers that need repaired and/or aligned so this would be of interest to me. Thanks.
I have to say this is an interesting little radio. I am not a fan of the design to be honest, but everything deserves the chance to survive :)
I agree, it should be given a renewal of it's life.
Restore it! Cool little radio.
I'd love to see it restored fully!
My first 2 duty stations in the US Coast Guard were LORAN transmitter stations. The transmitters were 275KW at 100KHz pulsed signal. If I remember correctly, the output plate voltage was about 18Kv. If we did not keep jumper wires across the spare capacitors that were in stock, they could charge to near their rated voltage. Many people have been shocked by high voltage across the body, due to not verifying a shorting jumper was installed before grabbing the ceramic insulators to pick up the 20+ pound, metal encased, oil filled capacitor. The connection studs were on top of the insulators and easy to set your thumbs on. Tubes, I love seeing them glow.
Hello in another field the mechanical electricity and especially the mains inverters the capacitors that were replaced were in short circuit
You've been teaching us well. I found myself saying "replace the socket!"
Agreed. And I was yelling, "discharge those capacitors!"
Awesome video Mr. C👍👍 As a less complex receiver with far fewer components and a relatively simple board, this might be a good teaching specimen for a more condensed video...or not. It seems most folks would like to see a full blown Mr. Carlson's Lab restoration but I'm kinda like you, 50/50...? If this radio warrants your time, yeah do what you like. BTW, nice antenna work. Lab is looking stellar, you've put in some hours. Thanks for the video and work, well done. 73's KC5NEX
Thanks for your kind comment Terry!
Yes to restoration! I always love watching your improvements on these old radios! Worth a new lease on life for sure!
It might be a fairly common, low budget radio of its day but it's a good example of a hybrid AM/FM with reutilized TV valves. TV valves are generally easier to get hold of so I think it's a great set to demo to those getting into radio restoration, and who better to show the does and don'ts of radio repair? 😁👍
Well now that you have it taken apart, and considering it's age, in my opinion a restoration, all things considered, is not a bad idea. Also, it can use a thorough cleaning too.
Cute little radio. Ideal for people who want to get into restorations I imagine.
One side of me says this radio deserves a resurrection/restoration, for there are many common radios like this that were made as minimalist sets like this one. If you decide to continual restoration on this Westinghouse radio, please put a good 14GT8 tube back in, so it's restored to it's original vintage factory condition. THE OTHER SIDE SAYS, LAY IT ASIDE FOR LATER AND GET ON WITH THE GRAND RECEIVER RESTORATIONS.
Note on the 14GT8 tube vers 19T8, the 19T8 was designed for discriminator FM detection where the third diode was used for AM detector. The 14GT8 was made for a Ratio FM detector where you did not need a Limiter stage before it and they had some other component do the AM detection, a cost cutting measure.
Nice to take a trip into the world of early circuit boards with tubes. Restore!
My grandfather had a radio just like that till he passed away. I remember him listening to Paul Harvey talk show each morning. I never knew what happened to the radio after he passed. You should definitely restore it.
Just relaxing on a Friday evening after a long day, and along comes a video from Mr. Carlson, making it way more awesome.
Yes to restoration! Not that it’s a special radio, but an excellent teaching experience. 👍👍
I have mixed feelings about fully restoring this particular radio. However, if you do, please use vintage test & alignment equipment, like a VTVM, EICO or Heathkit, i.e., the equipment most of us hobbyists might use. I'd especially like to see you use a vintage FM Sweep generator, like a Heathkit TS-4 or an EICO Model 368. Maybe you could show the procedure with and without using an oscilloscope. I know you've done this with AM alignment. Maybe you could use this radio to do a training session on different methods of FM alignment. Thanks for your videos! You were one of my main inspirations for attempting this hobby!
Restore it Paul! It deserves to get some more use and we would like to see the FM alignment. I can’t recall you doing many FM radios. Videos of good in depth FM alignments are few on TH-cam.
I am all for restoring this radio. I have an old 8 tube Philco am/fm radio that was given to me as "It was working in our garage, then stopped so you can have it" that I want to restore, but I've never aligned FM so I've been waiting to watch you do one.
I would like to see the tuning process, so my vote is restore it 👍
don't restore
Mr. Carlson those radio's kept me gainfully employed . As a teenager .
It would be amazing to see it restored. Especially to see FM alignment. We've seen AM alignment so many times in comparison.
I agree.
That's a really good point. I'd love to see an FM alignment. It may not be much of a looker, but it does have FM to be aligned.
Count me in on the "Yes, restore" side just for that.
yes, it should get a full restore, and the audio output tube should get a ceramic tube socket, it seems they put that weird metal pin one in there cause that tube gets too hot for bakelite sockets or any other types of composites but a ceramic will be able to take the heat of the 50C5 i mean they run HOT! 400+F
I've seen several FM alignment videos on TH-cam. Your expertise would definitely add value to the mix. YES!
Some cost cutting there, that kind of output tube socket I have never seen, seems primitive. The Görler marked FM tuner is German, and I have seen many radios here in Norway using tuners from that company
Have at it, Mr Carlson! Given it's functional and the case is in neat and tidy, it is worth preserving it for the future. Also, be great to see the tuning etc as that is something many of us will likely have a crack at during our own projects and restorations.
Sorry, Paul, but I just heard incredible Irony from you! At 3:28 , after you refer to present-day 'junk', you remove the back and reveal a single phenolic circuit board with NO chassis and NO isolation! :)
I say yes to the restoration to see the FM alignment process.
Would like to see the tuning process, so yes to the restore.
I say "Yes" to a full restoration!
🙂
Nice job as usual! One funny thing to do when restoring electronics is to build in a little smoke generator that activates when pressing a certain button. You can combine that kind of mod with a hidden web camera filming the event.
I'd say yes to the complete restoration.
MrCarlsonsLab and CuriousMarc, feeding my hoarding and repair of vintage HP test kit
I vote no for restoration, but I'd still watch if you did!
I am currently working on a similar radio. I say yes to a restoration and alignment. Curious about the fm especially.
Mr. Carlson, i love your videos. I think your videos are best-in-class. They are much better than any other similar type videos on the internet. I recommend to restore the radio please. 😊
I know more about tube socks than I do about tube valves but the clarity and attention to detail in your presentation makes every video a pleasure to watch.
The 19T8's filament has a higher resistance than the 14GT8's filament. The 19T8 will probably see about 23-24 V across the filament, and the rest of the string will run a little cooler. Need to put some shunt resistance across the filament to bring it down to 19 V. Mr. Carlson, I'm surprized, but gave ya a thumbs-up anyhow for the diode modding. 👍
Nah. Blow the dust out, put it back together and listen to the BlueJays on it until it dies again. Meanwhile....how about that SP600 receiver? Ehh?? !! Next up on the Great Receiver lineup maybe? Always educational and fun. Mr. C! Thanks!
It does need alignment for sure...new caps maybe. Do it, it deserves to survive even though it has a pcb and a bad dial routing. It seems to me to be a fairly low hour set.
Not a fan of the radio. My vote is to let it go.
Love your videos! Especially of the earlier radios!
Paul I would like to at least see how you do fm if with sweep and markers. Also the s curve. I have
watched alighnment with the sg80 sencore and bk415. Love to see your stuff.

Sure wish you would repair/restore more amateur radio gear. I have a Heathkit AR-3 and a National HRO-5 TA1 that both need some TLC to operate well once again. I need your ideas on how to work around some "unobtanium" parts in both. Thank You from a 45 year Ham Radio guy.
Nifty ... I wonder how many people are still listening to AM these days ..... I remember when FM was just becoming popular & my parents cars only having AM
That radio 📻 sure looks well preserved. All it needs is the electrolytic capacitors replaced. It’s either a White-Westinghouse, or just Westinghouse. At some point, their name underwent this change. FABULOUS circuitry. This definitely 💯 deserves to be in your living room, or somewhere it can be seen. Other than all the dust, it looks like 👍 it’s been well cared for. Your friend, Jeff.
Personally I'd say restore it, precisely because it is a 'cheapy'. I have a 'farm radio' that's been in my family since bought new in 1946, that had horrendous tube sockets that I had to replace - but that would have been post-war economics here in the UK. Originally cheap radios are often rare as (1) they often failed, and (2) they were likely to just be thrown away when they failed. So I say restore it!
Thanks, Paul. I say yes to refurbishing the radio if you want to. Were the older Probe Master leads not gold plated? All of mine are gold plated.
The tips on these are stainless, very hard metal.
@@MrCarlsonsLab Hmm. I love these Probe Master gold plated leads. Just a light touch is all it takes. No more poking and twisting to try to get a good connection. And as inexpensive as they are, it's really hard for me to take a lot of people on YT seriously when they can't even get some Probe Master leads. Maybe it's just me...
A nice presentation of a receiver that combines the box design of early radio and the front face of the 1960s. It certainly belongs to the development of radio. Thank you!
I'd love to see it restored if you have time Mr Carlson!
On another note I inherited an obviously very old Mini-Ball TL60 amplifier that has one MRF 453 Transistor in it which is no longer available. I can't find any info on that amplifier model whatsoever.
I'm told it doesn't sound very good on the air but I did manage to get out 7 miles on it where I couldn't with my base CB setup at 20 watt's. Originally it had very high SWR because the SO 239's were loose at the back of the chassis.
It has a nice little circuit board with a mic keying circuit and a bypass switch with led on the face. Also a couple small transistors as well as a couple Mosfet transistors at the edge of the board.
I changed one physically leaking cap on it but have not put it on the air again.
With it being old I didn't know if you might like taking a look at it or not?
Very selfish of me, but, YES! Please do a restoration on this..... Ok, the reason is that I just found an AM only Westinghouse yesterday! Almost the exact same tubes (except for one, I think) I may need a new tube or two -- no life yet. Thanks for all you do.
One ugly radio. Move on to the receivers!
You call it hideous, but it just appears like they designed it to look like a miniature console of that era.
Might be a neat project to restore it and enhance it a bit with some pulleys, lights, and anything else it could use!
I'd say you have too much on your plate already as to queued restorations. Do the more desirable units first. Then by the time you're a great grandpa, you can get back to this one...maybe.
Looking at that white plastic base, it's obvious this unit is the deluxe version with the "wood" housing. The cheaper ones would have had a matching white plastic upper housing.
Could it be this old technology was used because there waskan existing factory and even the good parts where cheap since they were not state of the art anymore ? So maybe a last tube ditch before everything went solid state? That could explain the discrepancies in quality. Which in itself would make it historically relevant for the period and worth saving.
I swear, your workshop looks like either, 1. the inside of the CIC in a heavy Navy cruiser, or , the CIC of a submarine.
would be interesting to see how great you can get it to work, with a full restore
I didn' think it sounded very good. Better, if you can afford it, to get a good receiver from the 1970s or 80s, and a pair of bookshelf speakers.
Nope. Don't bother with this radio. It impresses me as something built of left-over parts. It may work, but it will never be good.
I think it might be more useful as parts unless you want to show just how cheap things got. It's sort of ugly, and clunky, and not really an example of anything special, other than if they had spend a few dollars more to make it.. It is an odd combination of stuff done right, and not.
I know you're very busy, but if I was a master of your kind of wizardry, I'd surely fix that thing!
Crappy little radio...Of course crappy in that day is miles above what we have today. It holds no appeal for me, but do what you want. I would happily watch you restore it. Or maybe put the old tube back in it and send it to Shango, see how long it takes him to figure it out.
It is wrong to part things out. This may have been cheaply made, but it is still a piece of history, and we come here to watch you repair things, not to know that you will break them.
Use your talents on a more deserving set. Break this one down for parts. There's just nothing "exciting" about this poor set.
I'd suggest aligning it, but I think I'd skip a full restoration. I don't think it's that great. Unless you have a job for it, it works, that's good enough for now. I'd rather see effort put into some of the other things you have waiting.
I'm thinking Mr C should design a dial lamp that also changes to show signal strength.
TH-cam only offers a standard size thumbs up option, so I give my BIG thumbs up here in the comments
Everyone is saying yes restore it.. and I always vote yes... but in this case I'm not sure it deserves the effort... maybe just an alignment
I definitely agree with Paul's cabinet related comment, it's hideous!
First. Love your videos Mr. Carlson!
Glad you like them!
Cheater cord... that's a new entry for my dictionary 😁 Mr. Carlson is an excellent English teacher!
I'm looking forward to watch a full restoration video of this unit
I'd like you to continue with the restoration! I don't think I've ever seen you do an FM alignment, and I'd be interested in seeing your technique.
Yes a resto would be great i love your channel let us know what other hobbies you have seems like your always working again thank you from mich
I know that the 6t8 is a triple triode and that 19t8 looks exactly like a 68 in terms of the plate structure so I think it's a triple triode.
Technically it's 4 tubes all in one, three diodes and one triode. They got pretty fancy with this one, any more complexity and we get into compactron type tubes.
@@MrCarlsonsLab I must have a distorted recollection about that tube. Looking at a data sheet for it, I see that is in fact one triode and three diodes in there. Very misleading when you look at the tube's physical appearance though, as it looks like a triple triode. My RCA manual says "Triple diode, high mu triode". My recollection was from the 1970s, the last time I handled one of these tubes.
This is the runt of the litter, so to speak, and deserves a chance to show it can still do it ;-) I say "yes" to some restoration and tuning.
Electronics really aren't my thing, but I love your videos.
Aw, man, I want one of those snazzy "Mr. Carlson's Lab" Sweatshirts! Lookin' sharp!
Honestly, I'd give this one a pass. Not really an interesting radio to me. I'd rather see some more of the big receivers done.
The tube types tell you that the filaments are in series. OK, I'm showing my age.
Yes, please restore. It would be awesome if you could add a dial lamp and pulleys on the tuner string.
I say don't bother doing a full restoration to this radio. Use your time to do restoration work on some device that is more deserving of your efforts.
A great little survivor from the end of the valve era; I'd love to see a full restoration. I can't quite believe the cost-cutting measures they used, especially on the tuning string!
Hi Paul. I know that you know that when are going to do a job you should do it right, so I vote yes for a full restore!
73 de W2PND Paul
Paul, here's my vote for a quick restoration project for a possible new AM/FM lab radio.
Definitely worth restoring, if only to show us how PCB assembled radios should be worked on :)
It's not a great design given the thermal stress on the board and components, but still a nice vintage radio.
Dealing with PCB mount sockets, I always solder them with a scrap tube in. This way I won't damage the proper tube, and will still have the socket sitting there with minimal stress. Oh, and the board just asks for some compressed air.
Inductively coupled antenna is a great invention too :)
I always check the solder/joints on older boards, first.
I would say scrap it and take all the useful parts for more historically relevant radios.
It deserves a restoration, after all it's TUBES, it must survive!
Yes. I'd like to see a full restoration on this classic. Thanks!
Great video my master always a wondering on me sir thanks a lot Mr Carlson sir.
😊❤
I would like it to be restord im worken on a radio my self its got no radio but a buzzen somthin with the bar antana but i will get it thanks you
I’d say move on. Not a particularly interesting radio
To decide, maybe try to retrobright the plastic front first: If it comes back to a bright color then restore it; if it still looks grimy then to the spare parts bin!
Though looking at the insides and what's been done already, I'm leaning towards the _parts_ answer so that you'll have more time for bigger things.
I would like another old radio come back to life.
