Commentary
A stereo power amplifier for natural sound.
Bipolar, MOS-FET, and J-FET transistors are used in the amplifier circuit, and they are selected according to the appropriate position.
It employs an isolation structure that eliminates vibration and magnetic interference of devices that impair the purity of music signals.
It can also be used as a monaural power amplifier by bridge connection.
