Description
@
The stereo receiver of the solid-state design which constituted the Puri Maine tuner from an all transistor.

An input transformer was not used for the output unit, but the complimentary SEPP-OTL system is adopted.
Moreover, in order to prevent that a power transistor is damaged by short-circuit of a speaker circuit etc., the EPC protection circuit is adopted.

The 5-unit variable condenser by FM triple and AM Dual-unit is adopted as a tuner part.
Moreover, also in the weak-electric-current community area, little distorted reception is enabled by IF circuitry of the 2 steps of four-step magnification limiting circuit.

The FM stereo <=> mono-automatic switching arrangement serves as an automatic change with the pure electronic formula, and is automatically received by a stereophonic broadcast.

Attached circuits including an automatic-frequency-control circuit and a SCA filter circuit, such as FM and a muting circuit, FM stereo beacon, a headset jack, and a DIN connector, are carried.

The original inclination panel is adopted from the field of ergonomics.
