well, I'm only doing what the Traynor service bulletin says.
And I assume, if there's hum, then there's some current flow, so the tubes should be ok. I might be totally off here.
I wish I could figure out a work-around, but I'm guessing they tried to engineer a cheap and nifty standby circuit that didn't stand up. The switch won't withstand the vintage method, even if I could figure that out. I just can't figure out what happened to make it stop working.
BTW, this came in with dead tube and blown fuse. Replaced those and got it working fine. Now the standby doesn't operate. Maybe I'm missing another faulty component.
I'm lost.
Giving up, unless there are other suggestions.
thanks !!
