Commentary
A simple stereo power amplifier consisting of two ICs and one transistor.
The input stage IC is a differential amplifier with a current mirror load capable of selecting an operating current with a low distortion factor, and realizes a low distortion factor while maintaining a high gain.
Power ICs of the complimentary service stage are composed of pure output circuit of two stage Darlington connection.
Equipped with a relay type protection circuit that protects the output stage IC even if the speaker terminal is short-circuited.
Uses a low-distortion 2-power transformer power supply circuit with reversed winding and canceled flux.
