I'm assuming that the pulses are not at the input frequency. Correct?
Find the equivalent of R175 on the type 2 diagram. What's the DC voltage across it?

The pulses are not a input frequency, no sir.
Having a tough time finding a 910 or ? ohm resistor connected to a zener, and them not parallel

There aren't many diodes.
Post a couple of good quality photos of the drive area from various angles.

With the woofer connected, do you have a square wave (swinging both above and below ground) on pin 7?
If so, just measure the voltage on pin 5?
Is the voltage on pin 7 about twice of that on pin 5?

Are the solder connections on that or any other transistor in the drive circuit heat stressed?
Do you have any of those on hand? Or the KSC2690?

Perry I have replaced the 1027, 5551 and 5401. I had them and shotgunned them all. This is why I am on the forum. Because nothing worked.
I don't have a sq wave I have a sine wave. Swinging pos to neg. I have -1.3mv with secondary grd as ref. on pin 5 and pin 7 is -135mv jumping around.
Does the amp have an initial mute delay?
If so, check for the square wave on pin 7 before the end of the delay (will only be a few seconds).
How loud is the audio from the woofer?

It does have a mute delay, but there is no sq. wave. Right when I press the remote pedal have a sine wave. I don't have sound till after the delay
The sound is very audible. It changes frequency when I set a different frequency also
I found the input, what would I use for a ref ground for AC?

That's very low. Increase the level to at least 1/4v (250mv). Increase it until you get a square wave.
