AB  - A small-sized audio amplifier with high power and low distrotion has been developed. In the new system with a Class B output circuit, the power voltage supplied to the output stage of the amplifier is changed according to the input signal so that the voltage applied to the output element is controlled to a small constant value, thus remarkably decreasing the power dissipation of the amplifier. Through the new system, the total power dissipation of the conventional Class B amplifier has been decreased to 1/2, the size of the heat-sink to 1/5 and the weight of the set of 1/4, respectively. The new amplifier is highly efficient, showing a distortion of 0.01% (at 20kHz, maximum output) and S/N of 110dB (IHF-A network).
