Hi, I have here a RCA BA-31A for repair. I received it with the original caps that many of them was blown. I replaced all the electrolytics and all the resistor that was far away from their rated value.
When I turn on the preamp there's a output signal for about 2 seconds and then there is no signal.
I tested all the transistors with a simple LCR meter and all of them tested good.
Attached schematics, how can I troubleshoot this issue?
