I'm no further then I was 3 weeks ago except the 1K resistor doesn't fry any more after going through the RF section.

I've gone through the audio section with a fine tooth comb and using the troubleshooting procedures laid out in the paperwork. Most of the checks are on caps so I had to isolate them and because of that I just replaced all the caps in this radio.

Speaker voice coil, field and bucking coil are good. All the voltages are good. So I'm stumped on this one. Don't know where to go next. Bad volume control? Bad tone control? Had the volume control out and it appears to be operating properly. Tone control changes the tone of the motorboating. Like I said... STUMPED!
