Same here. I was pointing to the most likely suspect before he asked. I missed two of the replaced components. I'm sort of a perpetual novice, or pre-novice. I'm especially drawn to vacuum tube stuff. I have a few radios, a TV, and a portable turntable all from the vacuum tube era that all need work. I've started to learn the basics many times, but I eventually get sidetracked onto other hobbies, and forget most of what I've learned. I've been tempted to try the Patreon course. Have you found it course helpful for a novice? I was a Patreon of another channel quite a while back. At one point Patreon stared neglecting to send me e-mail notices. I was never able to get that issue resolved. It may be a problem with my personal mail server. If I was to sign up for something else on Patreon I might have to resort to using an alternate e-mail address.

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.

The moment you powered it up I thought, "60hz AC hum! Check filter capacitor(s) on the power supply."

A little hum!!! It's amazing how many radios still work to some degree after so many years. Good to see you try them out before changing parts... with the appropriate safety devices of course.

I'm detecting the Shango066 influence. Down and dirty, let's get it working then we can restore it. This video actually dovetails nicely with the Trav-ler video he released earlier today.

This is an excellent video for introducing troubleshooting to novices! Perhaps you could use this chassis to make several more "one-topic" videos (i.e. safety caps, AF amps, etc.) to help first-timers learn a proper sequence for restorations. Thanks for all you do for the community.

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.

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.

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!

Mr Carlson's your 1951 Radio Receiver is cool I like it

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 😆

Wow! That's a nice tiny oldie!

Paul's knowledge is amazing. His experience is priceless.

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.

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

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.

@@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...

It's lovely when a repair almost feels like it repairs itself. In between a tough one, it can feel like an oasis haha. Wonderful job as always on the audio, the content, and the filming of what you do and your willingness to share it with us. It can be refreshing to see "big stuff" as you've got here and the freedom to place things in circuit that wide. Mostly all SMD repair and thru hole for me.

I wish to watch your video daily. It's more benefits for my work

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.

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.

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.👍

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.

Hi Mr. Carlsen, if you haven't already do you think you could tell us a little about the equipment and software to do the audio part of your presentations? It's so crystal clear and well modulated I would love to know. Thanks again for your entertaining and highly educational broadcasts.

Very good demonstration . Thank you.

Another awesome video Mr. Carlson ! I learn more and more watching these !

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!?

Excellent demonstration and explanations and above all interesting. I’ve a very basic understanding of electronics but this has rekindled my interest. Will watch more of your videos .Many thanks for this.

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.

Excellent! Cool plastic for its age...

So glad I found this video. I recently found this exact same radio for $20 and it had all the tubes so I bought it. I haven't yet attempted a power up, as I hadn't even been able to find the model number.

Your opening question reminded me of a class I had to attend for my company years ago. I was a bench tech for Polaroid Camera company and we were training on a new strobe flash unit. For the test to complete the class they had 10 flash units with defects they had placed defects into. And we were to only determine the defective component, not make the repair, using test equipment and the schematic. One unit I opened had an Allen Bradley resistor swapped into the Chinese circuit board. I saw that, closed it back up, passed it onto the next guy, and wrote down the defect. Immediately, the trainer got up and came over to me asking why I did not troubleshoot the device. I told him that the Chinese do not use Allen Bradley style resistors in these units. He gave me credit for it anyway.

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..

Looking forward to another reconditioning video for this radio. Thank you.

Mr. C you are amazing!

A friend of mine gave me this exact radio, I have it on the mantle downstairs! I haven't plugged it in, but now it's time to open it up and see what's inside. I will be following along and restoring mine as well. I just took it apart, and all the parts are original! The speaker model number is almost identical, but I think mine is a little bit newer, it doesn't have the dogbone resistors I see in Mr. Carlson's unit. Also, the dial light on mine is off to the left side as you face the chassis, Mr. Carlson's is in the center. Funny how the rear label says, "only use genuine GE tubes" when there is a mix of GE, RCA and Raytheon tubes inside. I'm quite sure they have never been changed, judging from the dust patterns.

Wow, I just finished working on a model 423, the same radio, different dial scale. A very good performer !

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.

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.

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 .

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.

I miss the longer 1.5hr+ videos. I hope you have a couple of longer more in depth an detail videos in the works. I've been watching you for around 2 years now and I've always learned something from the procedure and troubleshooting process.

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
