Commentary
An FM/AM tuner developed by inheriting the ideas of advanced equipment such as circuit design and gyro touch tuning.
The IF stage consists of two composite ceramic filters and a 5-stage IF amplifier including a limiter stage. The ceramic filter has good phase linearity, little high-frequency distortion, and excellent separation and characteristics.
The limiter circuit consists of a gold-band hot-carrier type diode. The limiter is sufficient for the signal, the amplitude modulation component included in the IF signal is removed, and an excellent capture ratio is obtained.
The wood cabinet in the picture was sold as an option sold separately.
Also, there was an optional rack mount adapter sold separately.
