Well things seem to be getting worse !
Audio xformer primary opened up so I used one from a scrap chassis that had a 50L6 output. Measures 186 ohm vs 220 ohm on schematic, got my faint audio back. Will this xformer be OK for now ?
Measured 12CU5 pin 6 grid and voltage was 265 ??? R43 330 ohm checks OK. Is this right ?? Maybe that's what popped the primary.
This is a series set so if I take out any tube that will open the circuit. I have a few of the tubes for the 130 line so I can swap them out and see if there is any change. All tubes checked good.
This set also has a UHF tuner. Could that be associated with my B+ tuner issues ? Schematic 350-1 doesn't show it do you have 351-1 or for that matter I'm sure someone has 351-1 they could look at and post if it shows the UHF tuner.
