Hi,
A few answers/questions:
Spun the AGC screw around a few times both ways, no difference.
The service switch--same thing (had messed with that one in the past too).
Is it possible these new tubes could go bad so quickly after working so good?
(putting all the old tubes back in will be next project if the answer is Yes).
Most tubes light up strong with blue halos inside.
Have wiggled most of the tubes around a bit while the set was running, but no difference except for the 12HG7 V/O--loud popping sound in the speakers. Still see that spark in there under one pin.
Did try this too with no change or improvement:
Ground up some steel bar on the grinder to get metallic powder. Carefully dumped some of it in the 12HG7 tube socket holes to get better contact in there. Didn't help nor hurt. Removed most of it with a magnet.
Bryan--no pressure, promise! You could take as much time as you wanted. At least I know the CRT is still good. If that hadn't come back on after the new damper tube was installed, I'd probably bag this one.
PS, should I spray contact cleaner in that service switch and try again?
Thanks again for the advice and have a great 4th!
Carl
