8-track player service manual

[James <nyb@xxxxxxx>]

Hi,

Does anyone have the service manual for the stereo itself in 76 NYB's?
The stereo is a Motorola Mark IV Ser. 60631 2CH4508.  The number beside
the pentastar is 64469, so I assume this is the Chrysler part number. 
I've found someone willing to fix the thing, but its an incredible maze
inside.  Surprisingly, it has integrated circuits, an advance for '76.

Thanks,
James
