Thanks for the reply PB. I looked the amp over and moved some the sandblock resistor's wiring going in to 9L. I immediately got the proper resistances at 9 and b6. Then everything checked out but t22. I tightened down the transformer screws and got 0 ohms at t22. Voltage checks good ,leds light ,tubes light. Nothing but static out of the headphone jack. how due I check to see if the problem's the pot, vs headphone jack ,etc ?
