It seems strange to me that your radio is performing less than optimally, Dave.

I restored my 42-788 which is very similar, and it seems to play very well indeed. As I recall, its circuitry matched the schematic. I had no problems with it once I overcame the miles and miles of rubber-covered wiring and replaced all paper and electrolytic capacitors and many of its resistors as well. I understand that you did the same with your set's caps...so I have nothing more to offer at this point...
