Hi! So I'm having some issues with this amplifier, it has no blown output FETs or power supply FETs, but the output driver board keeps failing and it also takes out the power supply driver board as well, the last time I worked on it.
I've worked on the output driver board so often that a few of the Solder pads are destroyed, I've ordered some female pins so I can plug in and out the boards rather than soldering them in.
There were a couple of damaged TO 92 transistors that seem to communicate between the driver boards, I've replaced those. I also repaired a traces on the main board that were damaged from the glue they used to hold down the capacitors.
