Re: Infinity PS-12 Powered Subwoofer Fired Amplifier
Well, it was the C2 cap.
Replaced and now the amp works fine.

Re: Infinity PS-12 Powered Subwoofer Fired Amplifier
I am really sorry to revive an old thread, but I have an Infinity PS410 (same amplifier plate it seems as PS-12) with the same fault as DoubleD14's.
I have measured the C2 voltage and it is 5.82 - 6V. It drops to 4.5 V if I manage to make the relay click by setting the plate horizontal with the discrete components on the bottom.
I tried your advice to use a resistor on the C2 pins and the relay clicks nicely and the sub works. I do not understand what component is faulty? The C2 cap?...
