In this example, the restorer found a 100R noisy R in the AFC circuit.

True it's always possible. Probably a lot less so with 90s resistors than with the resistors in that early 60s Sony set.

I won't give up, at least not anytime soon. I fixed a shortwave radio once that took me years. I had to put it aside for awhile and the when I came back to it fresh it kind of clicked and I figured it out.

Although, this is looking pretty much like I'll have to brute force things to some extent.

All I have currently is some slightly wrong voltages, so I'll start there.
