Commentary

Compact size receiver.

The main amplifier uses a semi complimentary service OTL circuit that combines carefully selected transistors with excellent characteristics.

A low-noise IC is used for the equalizer circuit to increase the maximum allowable input.

The tone control section uses the Yamaha method with a 2-stage direct amplifier.

The front end of the FM tuner uses a 3-row varicon and a low-noise FET.

It is equipped with a loudness, tape monitor and speaker selector.

The AM tuner section is also designed with an emphasis on sound quality.

Equipped with two FM antenna terminals.
