It also comes with an FM stereo station indicating device so that you can find an FM stereo station.

The FM tuner section is equipped with a triple varicon and a double noise limiter.

The AM tuner section uses a triple varicon, a high frequency amplifier circuit and a ferrite bar antenna.

Since the preamplifier section is fully DC ignited, hum noise is suppressed.

It is equipped with functions such as loudness control, noise filter, tape monitor function, stereo phone jack, FM AFC (FM automatic stabilizer), etc.
