My ST35 is about 6 years old. Using PA774 power transformer. Also using GZ34 tube rectification. Amp sat for a few months and when I went to use it again amp seems dead. Tubes have a small light, but not full on like normal.
I'm measuring 120VAc going into my primary on the power transformer. I only get 3 or 4Vac out at Pin 10 at the board. So only 3 or 4 Vac between pins 9 and 10 at J1.
Has my PA774 fried? Any more ideas on what to check?
This is my second PA774. First one lasted about a year before frying. I'm on the second one. Maybe with tube rectification, it's drawing too much?
Any help you can provide would be appreciated.
