you are able to take anything you find and make it work . what I have learned from your videos is no matter how old or how beat up something is there is always life left you just have to bring it back to the surface . you are amazing and a man of many talents thank you for posting this great video

Really enjoyed every minute of that! I figured the outputs were overheating because of the low impedance speaker. It seems a lot of cheap early solid state stuff used high impedance speakers like 23 ohm or higher, I guess to protect the outputs which were probably running at the borderline of their design.

I have been binge watching your channel over the last few days and I have learned a huge amount on tv and radio operation. Thank you for making these videos and sharing your knowledge.

No waist of time at all: Didn't realize 45 minutes went by. Learned a lot...

Watching your vid's gives me courage to try this myself! A great hobby for my old brain to learn something new! Thanks much!

Very interesting and educational video Shango066. It's the combo of your personality, knowledge and unusual trouble shooting techniques that keep all of us coming back for more. Don't change that format! Thanks again and take care!

I actually grew up with that radio and remember listening for school closings on it.

I remember that radio from our kitchen when I was a child. A radio in the kitchen, so you could listen to trained newspeople, was standard back then. Now there are no trained newspeople.

I've been doing this stuff for 40 years, and I always learn something new from watching how someone else does it, so keep it up. Yeah, how do you replace all the cabs first. Cover comes off first! Actually, "siege" cap replacement can often cause more troubleshooting problems than it solves. I test caps and T-shoot first-then replace any old still working caps if I think they need it -it all depends. You have a great channel, thank you!

Great video ,i could watch for hour ,what you do with stuff that most people would not touch is fantastic.Watching you work is a joy

The poor little radio is crying to you in pain. :’(

Great video. I used to work in a tv and radio shop back in the late 60's. Brought back memories!! Loved working on that older stuff. Would love to see more. What about the Munson(sp) TV?? Did you ever fix it? I would like to see that work again.

Great video! Very entertaining and I even learned a few things while watching...

Educational and Entertaining! I appreciate your videos...thank you!

So cool repair, thanks and please do more like this

The motor boating part was funny 😂. It reminds me of a radio/cd player I had that started doing that really badly on radio & cd, so I EOLed it with a baseball bat. LOL 😂

OK, its 2021 as i watch this. Why the hell did youtube recommend this to me? not that i mind at all. i always learn something from your videos. its just weird to me how the youtube algorithm works.

Great vid mate!

Watched the whole video.. Time well spent!! :)

The output stage running "class f". Love it! Making a radio out of crap! How cool.

Damn cool man! Just to pull a broken circuit board and make it work. I like your outside the box thinking on stuff.... cheers! 🍻

The schematic use positive ground on NPN transistors instead of negative that make it looks confuse but it's very simple. The 1.4v is voltage drops across 68 ohm current limit resistor for output stage, when it play loud, the 1.4v will increase.

I've never seen a better method of "fast-checking" electrolytics. Thank you very much for this insight!

thx from germany for the video :-) love your creativ way for the psu :D

¡This is a Master lesson! I was so concentrated in what's was going up that when that electronic screech came up I almost died. By the way I love what you do and I'm reading all stuff I can find on tube radios and circuits but man I'm developing a mania of checking and picking radios and TVs at dumpers. 😁

It's not a waste of time, your video's are enjoyed by us,.

NPN Germanium transistors on the output stage? Hardly ever see NPN Germaniums.

That is great! I wouldn't mind having that. Only thing is the different voltage requirements. Maybe you could demonstrate making a power supply circuit.

That tag on the circuit board is an Arvin thing

Great video. I am so OCD I would of had to spray it all down with non residue tuner cleaner to get it nice and clean at the end of my work.

works really well nice job

Nice job!

Good stuff. Thanks.

It would be neat if you made a lucite case for this radio to show off your handiwork and ingenuity. Enjoyed the video.

i don't like people that a priori change things without thinking. i prefer rasoning that guide you to the root of the problems. Then, you care about performance. rememering you can not turn a crappy radio into a high performance radio. Like your way! hats

Very cool

Still love this video.

This is a fun one.

Magnavox speakers are typically 4 ohm as well.

I like the time waster videos you and radiophonenut

a smart idea from sears amazing

what about using a 470uf as a speaker coupling cap and 32 ohm speaker. is it worth replacing the output transistors with BD132 power transistors and replacing the other transistors with 2SA733 transistors.

That power supply at 7:43 is bada$$

Cute little radio

R17 was changed in value to adjust the current limiting or you changed voltage divider ratio elsewhere?

I think he has a Power Designs TP343 -or something like it. I have one, it's my 'go to' PS for lower voltages. Design of most budget stuff was driven by money back then. Just like now.

Old radio like "solid rock" less parts, more voltage supply rails... more coils... and give clear sound after restoring...

love the video! not everything needs to be upclose and personal, get a try pod.

Caps at the high end and coils at the low end please. Cool junk. Old Q pack bias.

This reminds me of that experiment where they kept a dogs head alive by substituting arteries from some kind of heart lung machine

THAT’S EIGHT SEVEN SEVEN! THREE FIVE FOURTY FOURTY!!!

AM radio is "analog internet" I can pick up SW stations from china, india.... and other places... with 3 transistor radio...

Traipsing up and down the AM dial…

😲 weird supply lines !!

a) nice power supply, what make and model is it? I've never seen one before! b) very strange power supply requirements, why on earth would they even consider designing it like that? surplus of cheap transformers with strange secondaries?

That is not a code used but the alliance, it could be an imperial code. It doesn’t sound friendly what ever it is.

No real airplane sounds in this video so the radio makes rc airplane noises at 20:03

Yes. 1

I bet it was dropped and the other side of the circuit board got lost or pirated.

That power/biasing thing is extremely stupid.

This radio requires a datailed cleaning before start to repair it, it is very damaged the best option is to restore it all.

Just curious...WHAT do you have against re-capping a radio or TV? It would save a LOT of messing around, LOL. Or is that the point...you like to "mess around" with it? I can understand that either way, but, it just seems that recapping makes sense if u wanna make it dependable and make it last....just sayin'...but you just keep on keepin' on, dude! I enjoy your videos immensely! And NO, it was NOT a waste of 45 min., I ALWAYS learn from ur vids and experimentation with stuff! Thanks for posting!

linux ubuntu i see

cheap looking tuner
