Seeing that a new transformer was installed, I would start there.
You need to verify if it is hooked up correctly.
The transformer itself can be tested by lifting (and marking
) the secondary wires.
There are 2 sets of wires.
The Heaters & the B+.
Vac of coarse.
If the transformer tests good you should start looking for a short somewhere.
Unpowered with the transformer still disconnected. -
If your tech is at his wits end I would suggest you find another one. I would not suggest you do much messing around without a technical background. It could get you killed. Theses amps are not that complicated. What was the original failure? Was the original PT an open circuit primary? If not, the original PT may be good and the tech is defective....Comment
