Good going resurrection, Shango style amost 🙂 The six tube setup with the RF pre-stage is a lot like they had in many tube car radios (rectifier there being a 0Z4), so once done up it will pull in plenty of distant stations.

The chassis will restore very well and the cabinet will look superb after a good clean up. It looks in decent enough condition, just very dusty. It's a stylish radio and judging by the performance you got from it pre-restoration, it's looking promising that it'll work very well indeed.

Good day from the UK. Could I ask, the original filter caps were 50uF but I think I noticed the replacements were about 450uF..... why did you go for a much larger value rather than replace values like for like? Is it because for a filter cap, within reason, you just want a decent amount of reservoir energy and specific capacitance is not so important? I assume originally, larger values would have been very expensive when the radio was made?
A ?? for you Mr Carlson. If a person has an AA 5 or 6 radio but living in a country that is 240 - 250v but without a stepup/down transformer What can be done to make the set compatible with the higher voltage area?

Love the Current limiting isolation transformer and variac supply. I never had one when I last plugged in a valve radio in the late seventies. Still got the burn scar on my wrist when I welded my metal watch strap to the chassis. Shocking what I got away with in those days.

Mr Carlson is the best when it comes to teaching vintage restoration, and I always recommend to people who want to learn. We've lived in a throwaway society for far too long and the people that understand are few and far between, so the more that learn the better. If a young person shows an interest I always try to encourage them. I'm in the UK so the only difference is the mains voltage. The technology and thinking is exactly the same so the teachings are perfectly valid.

Hi do like watching your restoration videos have you done work on vintage Radiograms with built in record player they were all the rage here in the UK back in the 1960s. Also would like to wish you a Merry Christmas and a Happy New year.
Nice looking radio - even older than me ... find it interesting that a miniature tube made it in with all the octals ....that receiver must be super hot receiver with the rf Amp prior to the pentagrid converter.
True enough with the 7-pin in mixed with the octals. My impression is that after WW2, there were so many tens of millions of surplus tubes available for pennies, if a manufacturer could save fifty cents sourcing a surplus tube vs a new one, they'd do it. The tubes in an AA5 radio, whether 7 pin or octal were electrically identical, just in different envelopes. Yes, GE made zillions of tubes, but maybe they never made a 12BA6 or 12BE6, or, going the other way, maybe they never made one of the usual tubes in an octal AA5 set.
@@m.k.8158 but why that particular tube and function. What drove the engineer's decision to choose that single miniature tube? Cost? Availability? Parameters? Location on the chassis?
@@tseckwr3783 well, since I've seen some GE sets with the chassis punched for octal sockets, but with miniature sockets installed in 1 or more octal openings, I figure that cost was the primary consideration-I doubt that availability was a major factor(but it's possible). The parameters are the same, and generally either type would fit, at least on the ones I've seen.
Thanks. Nice restoration video. I like it notably for the step-by-step approach, with considerations about the impacts (for example : explaining what may happen if you don't remove the failing filters, if you don't change these old wax capacitors...) Very simple set : only MW band, no magic-eye, no PU inputs, no fancy styling... I guess this radio was used as a secondary set in a sleeping room, a home office...
I remember when I was very young my mom took me with her when she goes to the store and in one shop I heard something humming and music playing with the hum LOL 😆. All day long that old line operated radio played in that little store. I also remember watching an old black and white TV made in the 1950s in the barber shop that had vertical fold over at the bottom ahhh those were the days. I miss those bad capacitor days LOL 😆
Во время второй мировой войны солдаты использовали радио из лезвия бритвы Gilete), катушки, карандаша и двух алюминиевых ложек в качестве конденсатора.)))
I'm seeing nine oddities in that radio. Of course if it were in front of me and I could see it with my real eyes, I could probably see more. Now I'll click play and see how well I did. EDIT Nice! I win, I spotted more. My prize is... well... diddly. But I still feel proud of myself as a beginner tech.
Hi, Every time I look your youtube films, I enyoi it very much, whane I was young I also was busy with tubes, I still love it, but I do not have the oppotunity to be busy with this right now, I would like one day to contruct my own amlipifier , anyway thank you, I'm always interreseted, I',m Marc from Belgium
Grett video. I'd like to see a restoration on this one. Because you don't get many All American 6's . Really appreciate your knoledge and explanation of these old circuits. Again, thanks.👍
When Mr. Carlson puts a title like "Can We Bring It Back To Life?", I wonder why didn't he write it as "Watch Me Easily Bring It Back To Life." Congrats on the content, I'm always delighted by your videos.
Oh my gosh! What gauge are those speaker leads!? They are like pieces of darning thread! General Electric really cheaped out on that! Mr.Carlson, from the North American champion of Heathkit builders and collectors, just kidding, you are the best!
I was not where of this filament flash . My collection of televisions and radios are in the 1930s age. One again you have come up with a ingenious solution
When fully restored, this radio should be a great performer. It has (6) tubes and a three-gang tuning capacitor, which means it has true tuned RF amplifier stage to really bring in weak signals. One thing I could never figure out on this style of GE model, is why they put a tube shield around the output tube!?
Over seventy years old and still works beautifully...amazing engineering. It makes me sad to see today's devices that work for 1 year...maybe...then thrown away.
Thanks for your video presentations. I "learned" how to fix radios when I was 15 Years old at my uncles Radio-TV Repair Shop. I was taught to repair by symptoms ,...ie: bad hum...replace fillter cap. Dead set,...check line cord and fuses, and tube filaments. You know what I'm talking about. After high school I went to RCA Institute of Technology and learned the theory. Other tech schools followed, like Bell and Howell which became DeVry , and finally I worked for Memorex and EMC in the world of disk drives and memory. Your videos are bringing me back many years as I am now 76 years young and still in love with electronics. Too many young people today reap my generations achievements and could care less about what brought them these marvelous devices they use daily. Well, I talk too much, but just wanted to say I'm glad I subscribed to you channel. BTW...your sites picture reminds me of something akin to a Space Lab. LOL. Well done!
Open filter capacitors are a pretty common problem with those old AA5 receivers. I notice that the receiver seems quite similar to the AA5's made here in the states; although, I've heard that in some areas of Canada the household current back in the early postwar era was 117 volts 25 cycles, which would require larger value filter capacitors.
I've had a few of these in different colors, and the volume pots are a weak point. Because the shaft is so long, it creates a lot of side-loading in use, which in turn makes the control become wobbly---at that point, it wears out the carbon trace inside
You knew it was going to be a " hummer" of a radio because the E caps (dual 50uF-50uF) are basically open circuited. Nice quick "resurrection" type video. Great candidate for a full restoration one day.
I am very interested in this one! I hope that when you do the restoration video that you include a schematic with it. Been trying to guess what the tubes are for. My last idea was RF amp, Oscillator, Mixer, IF, IF, Audio Output...or, possibly 1 IF amp and a preamp and Audio Output. Hold on a second...I forgot the rectifier tube!!!
Hi Mr Carlson! Merry Christmas and Happy New Year to You and All of Your Loved Ones. Thank You for a Great Year of Information and Learning. Bless You and Everyone in range of your antenna.
Just for fun you should try a slinky as a antenna. They claim it has 81ft of wire. Might be fun to see if it works and test if it has any gain from the coils and its bandwidth.
At least whoever replaced the caps didn't screwdriver it too seriously. I've seen enough of your videos to know AM reception in your lab is... uh... less than ideal. 😁 So, it still has sensitivity to it. Good radio! 👍
It was the fault of B+ supply,I had also repaired such types of faults in ,GE,gec,hmv radios about 45 years back in the year 1979,thanks.about 3 years back there were all types of valve radios circuits online,in u tube.but they are not available at present,alas.
This looks like 👍 a “home office” radio 📻, being of perfect 😍 size for there. Until about half a year ago (or a bit more) , I never 👎 really thought 💭 of these radios 📻 as a “Christmas 🎄 tree light set”. They do work just like 👍 a Christmas 🎄 tree light 💡 string. Very painstaking (as far as Christmas 🎄 light 💡 strings go). In either case (Christmas 🎄 light 💡 strings, or tube type radio 📻), this is a safety feature against further light bulb 💡 (or tube burnout 🔥), and possibly fire 🔥. This is a very nice 👍 radio 📻, in mahogany colored Bakelite. It came to me one ☝️ day, that Bakelite can be destroyed by cracking or breaking, but ya can’t melt, bend, or burn 🔥 it. I also don’t think 🤔 Bakelite suffers thermal (heat) or chemical (use and age)breakdown, such as from hot 🥵 tubes, or sunlight ☀️. I also don’t think 🤔 Bakelite fades, either (color). This is when GE made GOOD 😌 products, right here in AMERICA 🇺🇸, by AMERICAN 🇺🇸 workers. Nowadays, anything made be GE, is either rebadged from some other non-GE company, and are made in China 🇨🇳. Happy 😊 belated safe Christmas 🎄, and Happy 😊 New Year!! Have a very safe and prosperous 2022!! From your friend, Jeff!!
For the person who sees this video as a "first try," DON'T THINK THIS IS WHAT ANY SANE PERSON would do with a radio! This is a Mr. Carlson video! It is SO riddled with knowledge about what COULD go wrong, might go wrong or would go wrong that no one else should try this at all. Remember, Paul has a gazillion spare parts and such to replace anything which MIGHT be destroyed. You don't.
Hi there Paul - Hey-Hey is that so often the case, fix filters on HT & there's life to the little beastie ! Not an AC/DC wiley fan but, many were delightful in looks & performance. Especially if they have an Ext Ant connection. Regardless of complexity or simplicity I like your style & enjoy these short dittys very much. Those 1.5 volt tubed portables can give a 'head-scratch' if they've been in poor storage near the seaside or lakes areas - But fun to sort out.. How's about running thru one of them with AM/SW bands, sometime. Best regards, Tony in S-Africa...
Not bad at all for just replacing one two section Electrolytic cap on a radio that is a year younger than me. Thanks for the video Paul. Always great to see troubleshooting videos.
Good morning Mister a new lesson for me : the capacitor and the problem whith that ( ERS and value !!!) Thanks for your explication and respect for your khwolege !!! Sorry for my English langage but at 62 year old in France ...... Good for all and god bless you and your family .

Of course mr. Carlson.. u can mke anything work even if is not working, u can mke it wrk indeed.. u are the best I've ever seen so far.. perfect logic and comun sense.. thank you for your videos & knowledge God bless and stay safe..👈😎👍 Keep up the good destiny..
Hi, I'm working on a GE 422. I found a couple of resistors in my radio and on your video that are not in the schematic. On the 12SQ7 there is a 6.8M resistor on pin 8 going to I'm not sure where. There is also a 47M resistor on pin 5 of the 35l6 tube which I think bridges over to the 6 pin. I probably would have left them there but the values of each resistor was WAY off. As I said, neither resistor is on the schematic or even shows up on the parts list. Any ideas on what I should do?
Interesting that electrolytic caps in American stuff always go open while on European stuff they ALWAYS short...70% of times when you test a tube radio or tv that has been sitting for years the main filter caps will be shorted, even the small electrolytics short very often...i had a radio that worked fine before recapping and quit working after recapping, reason was that the cathode resistor on the output tube was open but the bypass capacitor was shorted so it was acting like a resistor and making the radio work great...after changing the caps the radio no longer worked :)
Did you know you can have that famous highly sought after expensive bumblebee sound? Just put a .1uf 630v new mylar film in series with it to block the leakage hahahahaha 😆😁 next time you get a hard to please tube amp guy try that on him
Paul, I was watching another site with a fellow that not only rebuilds old radios but is also a Ford Model A nut. He is also an amateur ham radio operator. I'd like to give him your call letters. Please let us see them. BTW, his name is Paul Shinn and lives in California.
Very good video, especially for someone new to the hobby and trying to develop troubleshooting skills. One question for you. What do you think was the reasoning for adding the black electrolytic cap? I don't have a real good view of where it was added. I am always amazed at what components I often see that were added by an owner or radio tech to solve a problem that may have been fixed a lot easier by just replacing a failing part. What do you think was the reasoning behind the added cap?
Mr Carlsons lab do you no ware I can get Russian germanium transistors for my zenith Trans oceanic shortwave receiver I want to restore it?😢😢😢let me no
In quick restorations like this, the coupling capacitor between the AF tube and the power output tube is usually changed automatically as well. But I appreciate that you are planning a full restoration and don't intend to use the radio in the mean time.
Another nice radio brought back to life, I love that! I have a question: what brand/type mike are you using during in- and outtro's? That microphone sounds brilliant. Or is it some kind of processing I hear? Keep up the good work, I enjoy your vids very much. Cheers from Holland!
@@MrCarlsonsLab That explains the richness of the audio, it's warm with excellent low, mids and high frequencies. That mike is a gem. Thanks for the answer, that's very appreciated 👍

this is so exciting... it is some what like watching the glasslinger repair channel and he can make all kinds of vacuum tubes with kool machine shop stuff... thanks, great video...:)
I work as a TV repairman and my boss is about 25 years older than me and someone brought in an old tube radio a long time ago and it needed of course a new electrolytic due to the hum and I sent it home. I kept the old paper electrolytic and taped it to my wall and my boss walked by and I asked him if he heard a hum. While he was listening I pointed to the old capacitor and he said ahh you like to horse around.
You mention all these old components that cause more bad than good, I am cringing at the antique store when they plug that 80 year old radio and says yes it works

9:25...the radio is HUMMING because it doesn't know the WORDS-?
(SNUCKER-SNUCKER-SNUCKER-!!)
I'm seeing nine oddities in that radio. Of course if it were in front of me and I could see it with my real eyes, I could probably see more. Now I'll click play and see how well I did.
EDIT
Nice! I win, I spotted more. My prize is... well... diddly. But I still feel proud of myself as a beginner tech.
Mr Carlson's your 1951 Radio Receiver is cool I like it
Hi, Every time I look your youtube films, I enyoi it very much, whane I was young I also was busy with tubes, I still love it, but I do not have the oppotunity to be busy with this right now, I would like one day to contruct my own amlipifier , anyway thank you, I'm always interreseted, I',m Marc from Belgium
Grett video. I'd like to see a restoration on this one. Because you don't get many All American 6's . Really appreciate your knoledge and explanation of these old circuits. Again, thanks.👍
When Mr. Carlson puts a title like "Can We Bring It Back To Life?", I wonder why didn't he write it as "Watch Me Easily Bring It Back To Life." Congrats on the content, I'm always delighted by your videos.
Oh my gosh! What gauge are those speaker leads!? They are like pieces of darning thread! General Electric really cheaped out on that! Mr.Carlson, from the North American champion of Heathkit builders and collectors, just kidding, you are the best!
I was not where of this filament flash . My collection of televisions and radios are in the 1930s age. One again you have come up with a ingenious solution
When fully restored, this radio should be a great performer. It has (6) tubes and a three-gang tuning capacitor, which means it has true tuned RF amplifier stage to really bring in weak signals. One thing I could never figure out on this style of GE model, is why they put a tube shield around the output tube!?
Over seventy years old and still works beautifully...amazing engineering.
It makes me sad to see today's devices that work for 1 year...maybe...then thrown away.
Thanks for your video presentations. I "learned" how to fix radios when I was 15 Years old at my uncles Radio-TV Repair Shop. I was taught to repair by symptoms ,...ie: bad hum...replace fillter cap. Dead set,...check line cord and fuses, and tube filaments. You know what I'm talking about. After high school I went to RCA Institute of Technology and learned the theory. Other tech schools followed, like Bell and Howell which became DeVry , and finally I worked for Memorex and EMC in the world of disk drives and memory. Your videos are bringing me back many years as I am now 76 years young and still in love with electronics. Too many young people today reap my generations achievements and could care less about what brought them these marvelous devices they use daily. Well, I talk too much, but just wanted to say I'm glad I subscribed to you channel. BTW...your sites picture reminds me of something akin to a Space Lab. LOL. Well done!
Thanks for sharing your story Vic, and your kind comments too!
Thank you for your time and knowledge. 21 in S.C.
you make it look so easy, been messing with an old german multiband radio off and on for the last 2 years guess its time to patreon up
Open filter capacitors are a pretty common problem with those old AA5 receivers. I notice that the receiver seems quite similar to the AA5's made here in the states; although, I've heard that in some areas of Canada the household current back in the early postwar era was 117 volts 25 cycles, which would require larger value filter capacitors.
I've had a few of these in different colors, and the volume pots are a weak point. Because the shaft is so long, it creates a lot of side-loading in use, which in turn makes the control become wobbly---at that point, it wears out the carbon trace inside
You knew it was going to be a " hummer" of a radio because the E caps (dual 50uF-50uF) are basically open circuited.
Nice quick "resurrection" type video. Great candidate for a full restoration one day.
Well, nice going Mr. Carlson! It seems I've watched so many of your videos now you've got ME pronouncing it "soul-der."
Excellent!
@@MrCarlsonsLab I do the same thing and proud of it!
Paul,
Your videos have the most amazing audio quality.
but this is summer blond all nice and happines repair. show us something really tricky, a really mess up thing where everything went terribly wrong
Look through my video's list.
I am very interested in this one! I hope that when you do the restoration video that you include a schematic with it.
Been trying to guess what the tubes are for. My last idea was RF amp, Oscillator, Mixer, IF, IF, Audio Output...or, possibly 1 IF amp and a preamp and Audio Output.
Hold on a second...I forgot the rectifier tube!!!
Hi Mr Carlson! Merry Christmas and Happy New Year to You and All of Your Loved Ones.
Thank You for a Great Year of Information and Learning. Bless You and Everyone in range of your antenna.
It's a general electric model file not found. ;)
Just for fun you should try a slinky as a antenna. They claim it has 81ft of wire. Might be fun to see if it works and test if it has any gain from the coils and its bandwidth.
GREAT CHANNEL, WHAT IS THE MIC YOU ARE USING
At least whoever replaced the caps didn't screwdriver it too seriously. I've seen enough of your videos to know AM reception in your lab is... uh... less than ideal. 😁 So, it still has sensitivity to it. Good radio! 👍
i got a radio just like that one but it is a different color
Very good demonstration . Thank you.
Love your videos! You have a great way of explaining the diagnostics and principles behind them. You ARE the Professor!!!
Nuther good'un Paul, have I missed something here or was that a new bit of testing gear you used? TFS, GB :)
Hi Graeme. I have had that for quite some time. That goes all the way back to that little chrome radio with the live case.
@@MrCarlsonsLab Getting old Paul! :(
It was the fault of B+ supply,I had also repaired such types of faults in ,GE,gec,hmv radios about 45 years back in the year 1979,thanks.about 3 years back there were all types of valve radios circuits online,in u tube.but they are not available at present,alas.
Thank you so much for bringing this video to me. pe1krx
Glad you enjoyed Arie!
This looks like 👍 a “home office” radio 📻, being of perfect 😍 size for there. Until about half a year ago (or a bit more) , I never 👎 really thought 💭 of these radios 📻 as a “Christmas 🎄 tree light set”. They do work just like 👍 a Christmas 🎄 tree light 💡 string. Very painstaking (as far as Christmas 🎄 light 💡 strings go). In either case (Christmas 🎄 light 💡 strings, or tube type radio 📻), this is a safety feature against further light bulb 💡 (or tube burnout 🔥), and possibly fire 🔥. This is a very nice 👍 radio 📻, in mahogany colored Bakelite. It came to me one ☝️ day, that Bakelite can be destroyed by cracking or breaking, but ya can’t melt, bend, or burn 🔥 it. I also don’t think 🤔 Bakelite suffers thermal (heat) or chemical (use and age)breakdown, such as from hot 🥵 tubes, or sunlight ☀️. I also don’t think 🤔 Bakelite fades, either (color). This is when GE made GOOD 😌 products, right here in AMERICA 🇺🇸, by AMERICAN 🇺🇸 workers. Nowadays, anything made be GE, is either rebadged from some other non-GE company, and are made in China 🇨🇳. Happy 😊 belated safe Christmas 🎄, and Happy 😊 New Year!! Have a very safe and prosperous 2022!! From your friend, Jeff!!
For the person who sees this video as a "first try," DON'T THINK THIS IS WHAT ANY SANE PERSON would do with a radio! This is a Mr. Carlson video! It is SO riddled with knowledge about what COULD go wrong, might go wrong or would go wrong that no one else should try this at all. Remember, Paul has a gazillion spare parts and such to replace anything which MIGHT be destroyed. You don't.
Hi there Paul - Hey-Hey is that so often the case, fix filters on HT & there's life to the little beastie ! Not an AC/DC wiley fan but, many were delightful in looks & performance. Especially if they have an Ext Ant connection. Regardless of complexity or simplicity I like your style & enjoy these short dittys very much. Those 1.5 volt tubed portables can give a 'head-scratch' if they've been in poor storage near the seaside or lakes areas - But fun to sort out.. How's about running thru one of them with AM/SW bands, sometime. Best regards, Tony in S-Africa...
Not bad at all for just replacing one two section Electrolytic cap on a radio that is a year younger than me. Thanks for the video Paul. Always great to see troubleshooting videos.
Wow! That's a nice tiny oldie!
Good morning Mister
a new lesson for me : the capacitor and the problem whith that ( ERS and value !!!)
Thanks for your explication and respect for your khwolege !!!
Sorry for my English langage but at 62 year old in France ......
Good for all and god bless you and your family .

Thanks for these short more frequent videos. I love the videos you post and enjoy having more opportunities to see new content throughout the week. Can’t wait to see some ham gear.
Of course mr. Carlson.. u can mke anything work even if is not working, u can mke it wrk indeed.. u are the best I've ever seen so far.. perfect logic and comun sense.. thank you for your videos & knowledge
God bless and stay safe..👈😎👍
Keep up the good destiny..

I learn something different every video you do, thank you!
My pleasure!
Hi, I'm working on a GE 422. I found a couple of resistors in my radio and on your video that are not in the schematic. On the 12SQ7 there is a 6.8M resistor on pin 8 going to I'm not sure where. There is also a 47M resistor on pin 5 of the 35l6 tube which I think bridges over to the 6 pin. I probably would have left them there but the values of each resistor was WAY off. As I said, neither resistor is on the schematic or even shows up on the parts list. Any ideas on what I should do?
Interesting that electrolytic caps in American stuff always go open while on European stuff they ALWAYS short...70% of times when you test a tube radio or tv that has been sitting for years the main filter caps will be shorted, even the small electrolytics short very often...i had a radio that worked fine before recapping and quit working after recapping, reason was that the cathode resistor on the output tube was open but the bypass capacitor was shorted so it was acting like a resistor and making the radio work great...after changing the caps the radio no longer worked :)
Where do you find all your project radios and equipment?
What's odd is, it finds me!
Did you know you can have that famous highly sought after expensive bumblebee sound? Just put a .1uf 630v new mylar film in series with it to block the leakage hahahahaha 😆😁 next time you get a hard to please tube amp guy try that on him
Paul, I was watching another site with a fellow that not only rebuilds old radios but is also a Ford Model A nut. He is also an amateur ham radio operator. I'd like to give him your call letters. Please let us see them. BTW, his name is Paul Shinn and lives in California.
hi mr carlson great vid,
Very good video, especially for someone new to the hobby and trying to develop troubleshooting skills. One question for you. What do you think was the reasoning for adding the black electrolytic cap? I don't have a real good view of where it was added. I am always amazed at what components I often see that were added by an owner or radio tech to solve a problem that may have been fixed a lot easier by just replacing a failing part. What do you think was the reasoning behind the added cap?
MR CARLSONS Your Radio Receiver is cool
MR CARLSONS Mary Christmas 🎄⛄
MR CARLSONS and a happy new year 🎄☃️
That's good with out liment
Mr Carlsons lab do you no ware I can get Russian germanium transistors for my zenith Trans oceanic shortwave receiver I want to restore it?😢😢😢let me no
GE made the best back in the days
Mighta missed your reference to it, but I'd never before seen a 3-gang tuning condenser with each gang a different size. That's a real curiosity.
Mr Carlsons lab my hobbies are painting pictures 🖼 and listening to shortwave and ssb iam thinking about getting my ham license 😊😊
In quick restorations like this, the coupling capacitor between the AF tube and the power output tube is usually changed automatically as well. But I appreciate that you are planning a full restoration and don't intend to use the radio in the mean time.
Another nice radio brought back to life, I love that! I have a question: what brand/type mike are you using during in- and outtro's? That microphone sounds brilliant. Or is it some kind of processing I hear? Keep up the good work, I enjoy your vids very much. Cheers from Holland!
It's a custom vacuum tube mic, and vacuum tube processor. Straight into the camera, no audio editing at all, digital or analog.
@@MrCarlsonsLab That explains the richness of the audio, it's warm with excellent low, mids and high frequencies. That mike is a gem. Thanks for the answer, that's very appreciated 👍
When finaly are we going to see a real action handling on Tektronix or Tube PA full restaurarion and repair video. Tired from simple switch on and check it on it works presentations
this is so exciting... it is some what like watching the glasslinger repair channel and he can make all kinds of vacuum tubes with kool machine shop stuff... thanks, great video...:)
I love how you ask in the title, "can we bring it back to life?" as if there was any doubt of your abilities. 😄
I appreciate the effort to put some suspense in the title, but you being you there's really not much. Thanks for the great videos!
I work as a TV repairman and my boss is about 25 years older than me and someone brought in an old tube radio a long time ago and it needed of course a new electrolytic due to the hum and I sent it home. I kept the old paper electrolytic and taped it to my wall and my boss walked by and I asked him if he heard a hum. While he was listening I pointed to the old capacitor and he said ahh you like to horse around.
Its amazing that you know exactly where to look for the problem just by turning it on and moving the dials without even getting out any type of meter.
You mention all these old components that cause more bad than good, I am cringing at the antique store when they plug that 80 year old radio and says yes it works
