This is a clone amp.
I am so frustrated with this amp, self oscillating is a pain, I just wish I could see what the drivers are doing with no outputs installed.
I replaced both banks of outputs (31N20D) and Q124 and Q125 (MPSA42).
As soon as it tries to come out of protect it instantly shorts the low side outputs.
What else besides Q124 and Q125 would make this happen?

It appears so. I think that was added in mid 2011. Email me if you have any other questions regarding the tutorial.

Removing the shorted output caused the solder bridge that fried the resistor. Then I replaced q124 and 125 and the resistor. Now no drive signal.
It is set for master.
I assume I need to find out why there is no drive signal first then see what happens when I put the outputs back in.
