Commentary

A 3-band stereo receiver.

In addition to FM and MW (AM), you can receive shortwave broadcasting (SW).

A compact size with 3-band reception and a wide range of functions is achieved through the use of rational component layout and compound pipes.

Power tube 6BQ5 is used to achieve output of 12W.

Equipped with a tape recording terminal.

Equipped with FM multi input terminal, multiplex adapter can be connected.

The tone control section allows volume and balance adjustment to be performed separately with one knob.

A silicon diode is used for the power supply.
