Commentary
A solid-state integrated stereo amplifier using transistors.
On the top of the FM tuner section, we have adopted a front end with carefully selected low-noise silicon transistors and FETs.
The output stage of the amplifier section is designed to reduce distortion.
Equipped with input / output terminal for tape deck and headphone jack.
