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 Electronics.- posted
