The highest quality FM/AM tuner was developed in preparation for the full-scale FM era by thoroughly pursuing high S/N and low distortion factor.

The front end is equipped with three highly input-resistant, low-noise dual-gate MOS FETs and a four connected linear varicon to ensure stable reception.

The IF stage uses a combination of three ICs, a crystal filter, and a block filter to improve selectivity.

The multi-circuit uses an LC-type carrier leak filter and an SCA filter.

It is equipped with a stereo only switch that receives only stereo broadcast transmission radio waves.

The AGC circuit is equipped with a 3-stage switch that can change the AGC characteristics, and good reception is possible regardless of short or long distance.

The AM tuner uses a 3-row varicon and a large ferrite bar antenna to improve the Radio noises rejection capability.

Uses a 2-meter system and has AM/FM/FM stereo indicators.

Equipped with FM / MPX noise canceller, muting switch, level control, level adjuster, FM auto function, etc.

The wood case was sold separately.
