Default Re: Electron Kinetics Eagle 2C amplifier problem

What we need are very sharp clear photos of both side of the PC board. If you remove the mounting screws from all the power transistors and the input and output jacks then you should be able to lift the PC board from the heat sinks so that both front and rear of the PC board can be seen.
The circuit design of this amplifier is somewhat unusual. Some of us who have worked on audio amplifiers for years might be able to tease out its schematic from looking at a really good set of photos of this PC board.
Because you have one channel that works it should be feasible to fix the other channel. The problem could be that just 1 component is bad.
