It has the same specification as the original NAD 3020 Series 20 Stereo Amplifier with minor circuit corrections and has additional MC cartridge input and a Mono button instead of Audio Muting. Early examples are marked 3020A Series 20 on the front, later just 3020A. Optional rack mount handles are available.
