Gang,
It hurts to admit, but I had a screwup. one of those capacitor blocks I re-stuffed appeared to have been re-stuffed incorrectly. Basically, I had a .01 cap going to the wrong lug.
I disconnected the volume control and i STILL had plenty of audio.
turned out I had a .01 cap routing audio directly into the audio pre-amp.
The 80 tube was replaced and when powering up, the radio did not play. I monitor ac current and my meter pegged as the radio warmed up.
That problem tuned out to be a bad 42 audio amp.
new tube, new rectifier and the correct capacitors, the radio is playing like it should. (shadow box still not working, but I can live with that.)
thanks for all the input guys,
I'm Mike, WB8VGE
