Greetings, I have a PSB sub amplifier I've been keeping going through the years. I've changed the transformer, replaced a few parts here and there, but now have a problem I've never encountered before.
There is no audio output from the signal anymore. If I turn up the volume knob, it starts buzzing they the speaker in a repeating sawtooth wave kind of sound and increases frequency as the gain increases.
I already tried a new transformer as it looked like one of the windings was bad, but this isn't a transformer issue in my experience. I'm wondering what might need replacing?
