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 UA-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.
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!
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)
Yes to restoration Mr Carlson! You have gone this far with this radio, so a complete restoration is my vote!
I'd love to see it restored fully!
You've been teaching us well. I found myself saying "replace the socket!"
Agreed. And I was yelling, "discharge those capacitors!"
Mr. Carlson those radio's kept me gainfully employed . As a teenager .
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
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.
Cute little radio. Ideal for people who want to get into restorations I imagine.
Yes to restoration! Not that it’s a special radio, but an excellent teaching experience. 👍👍
Nice to take a trip into the world of early circuit boards with tubes. Restore!
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.
Yes to restoration! I always love watching your improvements on these old radios! Worth a new lease on life for sure!
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've seen several FM alignment videos on UA-cam. Your expertise would definitely add value to the mix. YES!
Yes, full restoration with dial lights and magic eye added. Great channel, tanks for all videos.
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 say "Yes" to a full restoration!
I say yes to the restoration to see the FM alignment process.
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.
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.
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? 😁👍
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.
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 UA-cam.
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!
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 the restoration. You're brilliant man! Genius!
Yes. I'd like to see a full restoration on this classic. Thanks!
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.
I don't normally watch your videos to the end, but I was transfixed. So yes please do a full restoration.
Would like to see the tuning process, so yes to the restore.
I would like to see the tuning process, so my vote is restore it 👍
MrCarlsonsLab and CuriousMarc, feeding my hoarding and repair of vintage HP test kit
if doing a resto means more Mr Carlson videos then i vote yes 😁
I'd say yes to the complete restoration.
Bring this one back to life - It really deserves a restore and a life once again - great episode as always.
yes! entire restoration. she deserve it!
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.
Absolutely yes Paul, on the restoration of this radio. I love watching you do your magic on the older tube type radios. Thank you. Gene from Tennessee.
Restore! Nice wood case to refinish.
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. 😊
An excellent Shango style resurrection, Mr Carlson. Yes, please go for a restoration, it deserves it.
Oh wow, my parents had one of these when I was a kid. My dad would listen to the news every morning as we were eating breakfast.
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
Two problems can’t hide from the Carlsonator
I like that it looks like its in very good shape beneath the dust. Would love to see it restored.
I think this would be an excellent little radio to dive into. I’d say yes. Restoration and a Mr. Carlson alignment is in order.
Nice workaround with 19V tube with diodes! Yes, would love to to it restored. Thanks for all the great UA-cam videos, much appreciated.
Brilliant sleuthing...your knowledge and skill never cease to amaze me.
YES, MR, CARLSON. I VOTE FOR A FULL RESTORATION. WARM REGARDS, DREW
Please turn Caps Lock off before you comment.
Thumbs up for restoration
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!
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.
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.
very impressive repair, your knowledge of electronics is remarkable, I think that radio needs to see a new life. keep up the great work you are doing. thanks for sharing.
Everything Mr. Carlson touches will work like new. Do a full recap, id love to hear the results.🇺🇸
Absolutely YES! But after you finish the The Grand Radio Receiver Restoration Series!!
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!
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
Yes, please restore. It would be awesome if you could add a dial lamp and pulleys on the tuner string.
The fact that the inside looks like its a different model that is upgraded by the wood cabinet is interesting! and yes this radio deserves to live!!
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.
Great repair!!! Make a restore. 👍👍
overheard in the FM section: "...Bellingham this 4th of July weekend..." Spent the afternoon of the 1st at the Spark Museum in Bellingham. I'd guess that anyone who is a fan of this channel would enjoy a visit there. Yes, please do a full rehab on this radio!
It deserves a restoration, after all it's TUBES, it must survive!
was ready for bed and Mr C uploaded a new video , awesome
Aw, man, I want one of those snazzy "Mr. Carlson's Lab" Sweatshirts! Lookin' sharp!
That is a fun little project and learning to get it going. I would be a Yes for restore. - New Shop radio.
Interesting way to see printed circuit board with tubes. I say yes to restoration. Love to watch your channel. I own a electronic repair shop in Brazil and i often make a repairs on HDMI boards of modern receivers like Denon, onkyo, etc. I love the challenge to repair this type of equipment.
Mr Carlsons lab your Barn find Am FM tube receiver from 1960s is awesome my friend 🎉🎉😅😅😊
I agree with most of the commenters in saying that this little radio deserves to be reborn. It's a good example of a hybrid tube/solid-state design yet it still retains most of the parts that are in the older tube radios. It's also more typical of the 1960s radios that restorers today might have had as children and kept in their parent's basement just waiting for the day when they could bring it back to life. Definitely worth a restore, IMHO.
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. 👍
Awesome as Always.... I would love to see this brought back to Service... Pleasure to watch and Learn
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.
Please do a full restoration. Let herr live. It will serve as a very good project. Go for it.
I like to see all restorations. So I vote to restore it. Especially since it combines old and new technology.
You certainly should restore this radio! It serves as a stepping stone along the road between sparkgaps and today's SDR's
i always appreciate the commentary the goes along the actual troubleshooting and fixing
I'd love to see a restauration of this little radio !
Great video my master always a wondering on me sir thanks a lot Mr Carlson sir.
😊❤
An opportunity for a Mr. Carlson restoration? Yes, please.
I would say yes as well, reminds me of my parents Am/Fm radio my first experience with the magic of the clarity of Fm of classical orchestral music!
I love the wood case for radios and it is interesting that it has FM. So yes on restoring this radio.
I think that since this one has pretty much survived and with little work, functions, it deserves to continue on. I keep watching here to learn more and more and get more confident. I have a few projects I want to get into sooner rather than later, starting with an RCA Victor 9x641 I found buried in my grandparent's garage. Complete, but the top of the cabinet is cracked, so I figure it's a good one to learn with.
Love your coax switch. nice troubleshooting tips. Thank you. Yes to restore please. I have an old GE 1955 model 416 am radio to troubleshoot. I appreciate your efforts on these "simple" projects.
Where did you get that coax switch Paul? Haven’t seen anything like it in catalogues.
YES! Full restoration!
I say restore it all the way. I love to see old things brought back to life.
I apreciate especially what you do to repaire old tube tuners
Love these Videos! Makes you wonder who is listening to all those AM stations during the day..
I know most are wanting to see you save this relic, but I feel your time and money is better well spent. As you say, it's a good "parts" resource. I feel it would cost more to restore it than the unit originally cost. You're correct, A lot of cost cutting by the bean counters back then.
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.
Yes, please do a full restoration and FM alignment. I would love to see that.
Paul, here's my vote for a quick restoration project for a possible new AM/FM lab radio.
I just picked up an RCA RJC30W that looks similar on the outside to yours (but a little cleaner 😂). For $4, I was thinking if it didn't work I would just use it for parts -- I was planning on using the tuner on a crystal radio. But somehow this thing still makes humming noises. It's still alive so I can't justify killing it! Your video has given me hope that I can repair it and make it fully functional.
I actually really like the look of that set, would be well worth restoring.
UA-cam only offers a standard size thumbs up option, so I give my BIG thumbs up here in the comments
A very neat job. I'm impressed by your diode modifications for the replacement tube. A lot of those old tuner strings are a nightmare, especially if you have to work out how they should be put on. The problem also with a lot of these small tube radios is the heat build-up inside, which is probably the cause of so many of the soldered joints going bad.
