Dumont "Scarlotti" 170011 63C14 Console Stereo Schematic Request

I've a head end unit from a console stereo that is in the shop for repair (one channel not working).

I've looked all over for a schematic for this unit and came up dry.

Can anyone point me to a source for this documentation?

Below is customer photo of faceplate and below that are chassis photos I took.
