<DIV><FONT face=Arial size=2>I have resurrected a PS-1175 12 volt power supply
that's been in mothballs for a few years. When I fired it up I remembered
why. It is only putting out about 4 volts DC. Voltages out of IC1
are all messed up, so I'm assuming that's where the problem is. My bigger
problem is trying to find a cross reference for the IC which is Heath part no.
442-625. All I have of the manual is the schematic. If anyone knows
what this cross references to, or has one of these IC's they can part with,
please let me know.</FONT></DIV>
