Yesterday I was playing channel 3.
Then I switched to channel 1 and no sound ?
No sound either on channel 2 but I still have sound on channel 3 . The no sound state is accompagned with increased hum.
BTW
channel 3 was in 90W mode,
channels 1 and 2 were in 45W mode.
So I figured that V1 is OK if channel 3 is good.
It should be a power tube . Since the problem is in 45W mode
That might be the two inner 6L6 that are broken.
I replaced them , and the problem still persist. Channel 1 and 2 cut off rapidly , randommly. I can play and then nothing.
I am thinking now of a bad rectifier tube.
Am I in the right way ?
