I need a schematic for a Kustom J695 two channel amp head.  S/N is 10762

The amp had one bad power transistor (replaced with a NOS unit) but has low volume and distortion when volume is set high.  Without a schematic, I'm just reduced to guessing.

There are no markings on the PC boards as to what number they are.  The amp uses three power transistors, the first of which is connected to the preamp board with the other two paralleled from that.  The audio board is mounted on three points to the chassis bottom via 90 degree tabs.

Any help would be appreciated.

Thanks!
Tom
