I removed the back amplifier PCB from the center section. This photo was taken just before reassembly.
Here is the removed board all cleaned up. You can see the components are nice and uniform now. New
capacitors installed, and the board was washed front and back.
Here is the power supply board, lifted from the frame to allow clearance for the soldering iron. I had about 3/4"
gap between the frame and board.... just enough!!!
