The Philco 41-231 Still Sings Beautifully!

[TUD1]

Well, that schematic I drew looks simple enough. (Anything I draw is simple.) So I guess I will have to order two more capacitors, but that's okay. I went to Lowe's today and got some heat shrink tubing in preparation for the big recap.

For yours to work like that, I'd bet that the electrolytics were replaced, even 50 years ago.
If you're concerned about recapping, do one at a time.
Do the electrolytics (power supply filter caps) first.
Take a picture before you remove the old cap.
Power it up to verify you did not make a wiring mistake, then do another.

With what you'll learn, I bet you be doing TV sets before you know it.

I was working on, which is probably, the smallest five tube superhet that Philco made. A model TH-4 from 1939. It was made to retail for $9.95, which was quite a bargain. The newer models were PT25 and a few variations.
A really good performing set and a lot of them survived.
That bad part is, it's extremely nasty to restore. Every inch of rubber wire has to be replaced. Plus, the chassis is only 4.5"X 8".
