Restored July 2022
When I first obtained this amplifier the outputs were running very hot and the existing thermal compound had dried out. Bias was running at approximately 180 millivolts. Upon closer examination I found that the bias resistors were open and trim pots not working properly. Resistors and trim pots were replaced. New thermal compound was applied to the power transistors as well as new insulators installed.
The unit is now properly biased at 6 millivolts both channels.
