DC voltage is 7/8 mV.

Just tested it out with my oscilloscope, as far as i can tell everything is fine. I played a 2000hz sine wave and the reading was steady and the waveform smooth. I tried it on my other amp and got the exact same response and reading.

Now that the amp is opened up and I can put my hand on the heatsink, it is definitely getting very hot. Possibly up to the 85C needed to trip the thermal breakers. I don't have a meter to measure temp, but I can only keep my hand on the heatshink for about 3 seconds before significant discomfort.

Any other ideas?
