If you twist the output filter inductor, does the noise change?

Do you have a 80-100k triangle waveform on pin 4 of the defaced IC that's NOT near the blue crystal?

If I'm not mistaken, kicker always uses pin 4 for the triangle waveform input. Confirm that it's not on pin3 either (in case this amp is different). This IC is an LM361.

If it's not on 3 either, confirm that you have a square wave signal on most of the pins of the defaced IC (mc14060) near the blue crystal. This IC should have 12v on pin 16 and pin 8 should be at ground (secondary ground).

Also confirm that you have 12v on pins 1 and 7 of the LM361.
