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.
