Commentary

This is a multi-purpose pre-main amplifier that covers the functions and contents necessary for the enthusiast use.

The power amplifier section uses a quasi complimentary service SEPP circuit.

The equalizer circuit is a 2-stage connected NFB type using low-noise silicon transistors.
The tone control is an easy-to-use Klix/Klukš top type.

Two lines of Tape, Phono, AUX and other input terminals are installed.
It also has a microphone input.

The preamplifier section and power amplifier section can be used separately by the switch on the rear panel.

Equipped with auxiliary circuits such as high / low filters and loudness.
