I'm selling a rare Superscope stereo/quadraphonic amplifier. It dates back to 1972 and is in excellent aesthetic and functional condition. It's original in every part, except for the power cord, which I replaced for safety. The only detectable defects are a few small scratches on the exterior, which are documented in the photos.
