PS-1175 Help Needed

[The Boutwells Bill & Mary]

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.
