    Hi,
    Anyone have the schematic for the amplifier board for a
    Kurzweil Mark 10? All of the schematics would be great
    though right now I just need the main amplifier board schematic.
    Thanks,
    Me

    Following up my own post heh.
    Problem was a speaker shorted to zero ohms, never heard
    of that happening before. It blew the speaker fuse
    for that channel on the circuit
    board and burned open the circuit
    board connection
    on one of two very large electrolytic capacitors on the
    power supply board connected to
    that channel which caused a hum when the
    fuse was replaced and the speaker replaced. I had
    to take the circuit board out and flip it over to see
    the burned part.
