Belles II Amp

I recently inherited a Belles amplifier. The faceplate reads: "Belles II Stereo Power Amplifier," and the back of the amp reads: "Belles Research Corporation, East Rochester, New York, USA." It is a small amp, roughly 15" by 10" by 5". I can't find any info on this amp...any info anyone might have would be appreciated.
Call Dave Belles(Power Modules.) I'm sure he can answer your question.
I owned on of these. 40 wpc @ 8ohms. 80 @ 4ohms. I got the information from Dave Belles himself.
