After moving a ton of blocks and building a retaining wall, I decided it was radio time again. Today, starting to look at the smaller component recap, and that took me to the cluster around the tone switch. I started to replace what I saw, then had cause to refer to the schematic. Oh deary me, none of this looks like what I'm working on..

Things changed from a happy-go-lucky soldering session to a sketch, trace and play detective. Our arch-enemy had been at work, clipping out some caps entirely and putting in entirely different values for others. I think now I have discerned how this was put together originally, and how the parts were arranged.

I probed around some of the resistors while I was checking things over. Many are far out of tolerance, including a few crucial ones in the signal path.

I mentioned before that the friend who gave us this set asked me, many years ago, to see if I could help improve its reception. Given the poor state of parts, and the mixed up efforts at repair/restoration it is not surprising that he wasn't satisfied.

Next session, in a couple of weeks, I'll sort out the tone circuit, and continue the work to recap and replace resistors.

Cheers
