I sure hope someone here knows these radios. Schematic (or sorts) is available on N/A.
When I got the radio, it was DOA, totally shorted input filters. After a lot of fun, I finally replaced literally every paper cap and every composition resistor. The radio now works, sort of.
The problem is, it has NO AGC action whatsoever. I can't connect even the tiniest antenna to it without it overloading on most all stations (and by overloading I mean the front end is totally swamped, cut off completely!)
Add to this, when I turn up the volume, it starts to either warble or motorboat, depending on station strength.
The AGC section of this thing honestly confuses the he!! out of me. (Shoot, those 'power detectors' are sort of confusing, too.. but at least I've figured out how they work...)
So... if anyone has some suggestions, I could sure use them.
TIA
