Stereo power amplifier.

Symmetrical triple is used for the circuit, and the strain is reduced by the perfect temperature countermeasure.
By using symmetrical triples, the output current can be controlled simply and effectively. Moreover, the voltage can also be controlled. Therefore, the output transistor is protected without a protective circuit that would adversely affect sound quality and increase the cost.
