Belles 150 Schematic - Service Manual

Looking for a schematic for the Belles 150 power amp.

Need the original model 150 repair manual from the early 1990s.

Not the 150A and Hot Rod 150A, both of which came after the Belles 150 without an "A"

The "A" circuitry is totally different, so those schematics will not be helpful.
