    Boston Acoustic MSUB no sound output(pics)

    The off/on/auto switch was busted so i forced it into auto mode and now the blue light comes on but i don’t get any audio output. Does anyone one have any experience repairing this amplifier? I looked it over, checked some the of output transistors, some of the power resistors and cleaned that nasty conductive epoxy glue stuff off but not having much luck in the trouble shooting department.

    I did however find a part of the PCB that was discolored from heat
Working...
