Pleasde read post #80 and view #81 I forgot to post the pics with post #80.
Sorry for the confusion.

Just a 100Hz signal no load.
Do you want me to hook the 80 watt 2 ohm resistor the output terminals and post a new photo?

Leave it directly connected to the supply but connect it to a speaker or dummy load and post a photo of the defective channel driven to clipping.
I cant it maxes out my power supply before the signal clips.
When I get to about 1/4 volume I am drawing 60 amps thats all my supply has, it kicks my supply into protect.

You connect it to the speaker terminals like you would a speaker. You only need to load the distorted channel. It doesn't need to be a 2 ohm load. It can be a 4 or even an 8 ohm load.
Thats how I had it hooked up.
I have 4..... 8 ohm resistors wired in parallel, 4 leads to one end and 4 leads to the other end. I hooked a terminal of the amp to each end.
I only had it hooked to the bad channel. Maybe a 2 ohm load makes the amp draw to much current?
I guess I could just use 1 and do an 8 ohm load that probably wouldnt draw much current?
Im sorry Perry I should have been more specific, all parts are in the circuit except D202.
The load signal you are seeing is with D202 removed.

Try this with both a higher and lower frequency signal. Does the distortion always happen precisely the the bottom of the waveform?
Is there possibly a small ceramic capacitor near the components that were replaced that was damaged?

Amp connected directly to supply, all parts except D202 in circuit, all 3 jumpers installed, 8 ohm load, scope setting 2ms/20vd.
1st pic: high frequency
2nd pic: low frequency
It seems to be more sensitive to the higher frequency.
The lower frequency still kinda looks funny at full volume.
