1965 Sears Silvertone AM-FM tube type radio repairs

I replaced all electrolytic and paper capacitors, installed a new silicon diode, and resoldered bad solder joints on the circuit board.

Beautiful radio, nice repair! It's always fun getting them up and working good again. Everyone is just a little different, that keeps it interesting. Sound really good.

Thank you! This one actually has 2 unusual features:

A 100 ma filament string for the RF and IF tubes using 18FW6, 18FX6 etc.

and a push-pull output with 2 50C5's and the 12DT8 FM converter tube in a separate filament string. I have never seen a push-pull transformerless table radio before.

What's with the funky FM band light fading off and on. Is it supposed to do that?

[retrochad]

I'm not sure why it appeared to do that...it seemed to look OK when viewing it in real life. It may be something weird going on with the camera but it appeared OK on the radio itself when I played it this morning.

Cool radio! Something like this would be set on top of the TV eh?

Haha imagine a big huge giant version of this radio, like the size of a full size console, complete with the mega size dial and knobs.. LOL im strange haha

Thanks! We actually have it on top of the piano at home now.

RCA actually made a 9" b/w tube type TV in the style of a large console! This is kind of reverse how you are thinking though hehe!

Thanks for this video. My parents bought Silvertone B&W TVs and we had a Silvertone portable 1940s radio with an appearance of being inside a cosmetic luggage piece. They are all in dumpster heaven now.

I really want to make an FM tube radio, were can I find a good schematic?

@jefferyb304 I don't think so. Keep in mind that they were testing brand-new radios. The thing is, almost all consumer-grade tube radios from this era have some kind of very low-level hum, even if the electrolytics are brand new. Most of the time, it's very, very minor, and not audible at all when the volume is turned up even a little bit. I'd venture to say that CR was being very nitpicky in its review of these sets.

@retrochad I have a Motorola transformerless table set with push-pull output. I believe it uses a pair of 35C5s. The set is from the late '50s or early '60s, like your Silvertone. As you know, push-pull is rare in sets of this vintage.

nice radio, 2-way speaker system.

I like the fading on and off effect on the power light

I purchased some Consumer Reports Magazines from the 50's & 60's. I was reading where they tested table radios and with some models they said they noted a hum. Could those old filter caps have really been that nasty ?

I have a radio similar to this, it is a Sears Silvertone. I just don't know the year.
