Anyone's got the schematic diagram for Kenwood KRX-693?

Question

I own an old Kenwood KRX-693 amplifier. There seems to be some problem with the power supply so they need the schematic diagram and an IC - D75112CW. I searched literally everywhere on the net as I could for the diagram, but din get it. If someone's got it, please let me know, or at least tell me where I can get it from. Thanks a million.
