    A power surge literally blew apart the power supply transistor,Q801, a
    2SK2917LB. There is a diode D862 across this transistor that was
    shorted. Also shorted was D824 which is across the output of the
    regulator IC801, AN8029. IC 801 a PC123 the opto IC was leaking as
    well. I am going to replace the AN 8029 along with the other parts
    since its output had a shorted diode across it too. Has anyone seen
    the power supply mosfet actually blow apart on one of these things
    before? I have no schematic of this set and was wondering if anyone
    had one that they could share with me. It would be really helpful to
    be able to see whats in there. Thanks a lot. Lenny Stein, Barlen
