¥ 63,800 (around 1976)
Commentary
A pre-main amplifier with a stable circuit configuration and careful consideration of the layout and wiring of the circuit board.
All stages of the power amplifier section use direct connection pure complimentary service OC system.
The first stage is differential amplification with dual transistors.
A 10,000 μ Fx2 capacitor is used for the power supply.
The equalizer amplifier uses a direct coupling method and dual FET.
Equipped with high-precision detent volume.
