The HA-3700 was a stereo amplifier manufactured by the Hitachi Corporation of Japan in the early 1980s. The HA-3700 was 35-watts per channel rms with an 8 Ω load. These amplifiers had the Super Linear Circuit feature, which was Hitachi’s solution for solving the problem of crossover distortion inherent in push-pull audio output circuits.
