RCA Victor RJC61W

[Puddintane]

Does anyone know anything about this particular RCA Victor radio Model RJC61W? The radio works pretty well, but it does have a hum across all inputs: AM, FM, phono, and tape, although I haven't yet actually connected anything via the phono or tape inputs. This is a screen grab from the internet, but it's the same thing.

That's a pretty common problem in older radios The first thing I would do is replace the big filter capacitors.

Would anyone, by chance, have a schematic?

I have the same radio and just fixed the problem with the buzz. There is a big quad capacitor (4 filter caps in one) that I replaced with four discrete ones. If interested, I can forward to you the procedure and the caps I used. I got the electrical schematic from https://stevenjohnson.com/ for $10.

Sure, I’d be interested. How about posting it here so that maybe someone else might benefit from it too.
