Ok then run on 117 and test....i guesss alll caps are replaced except for the single wire can that just says a part number on it...no value on it..havnt looked it up on parts list yet.
I do still hear vertacle buzz when picture is faded out and or 6bg6 isnt lit. Can also vary the buzz with front control knob. Makes me also wonder if a resistor is getting hot and opening. Restors are next anyway.
Fascinating! I just figured the high voltage was going away when I cranked it to 117 volts. Its not. Screen lit about 100 volts measured and high voltage is about 7k. When I crank it to 117 volts the high voltage goes to 9k which is what schematic says. Weird its like somebody cranks down the brightness to zero with in 5 seconds after I crank up line voltage to 117.
I did manage to check the 6v6 audio output tube to see if somebody biased it differently because it had a 6k6 installed. Seems wired for 6v6 so I popped in a 6v6.
