Ok. Let me look this over this weekend.
As of now I’ve traced every wire from the top of chassis to underneath. See nothing amiss. The radio powers up with no drama but no audio. Someone has subbed a 50a5 for the 35a5. Correct tube on order. Fixed the dial string temporarily.
The two stray black and white wires remain a mystery. They are on B1 and B2 as best I can tell. I’m almost to the point of buying a second unit to diagnose the problem. Pulled the band switch to get a better picture.
Power switch works correctly. Filament voltages throughout and pilot light works.
