Lafayette LA-975 Schematic needed

[Mopargirl73]

New to this forum....in need of a schematic for a Lafayette LA-975. Got our hands on one for free but needs work. Would love to tinker with it and learn but
the online information available on this amp is very limited. Any help is greatly appreciated. Thank you !

The LA-975 was introduced to add 4-channel access to conventional stereo receivers and amplifiers.
It's catalog tag was "4-CHANNEL SQ DECODER/REAR AMPLIFIER". I think we had it in two of our large catalogs 1974 and 75.
There was only one manual for it. It was mainly operating and setup information but there was some service-related information including schematic and parts layout. The preamp and power amplifier design was unremarkable and followed the circuit design strategy used in other Lafayette receivers and amplifiers. From what I remember, we didn't sell that many over its life-cycle and don't recall many coming by my service bench for repair.

Thanks for the info, currently using as a stereo amp. Found other Lafayette schematics, good to know that they were similar.

Got it fixed... the contacts in the power switch were corroded and had a crackling output on the speakers, DC on the output jacks jumping all around. All good now. Never did need the schem, but thanks anyhow.
