Commentary

Easy-to-use FM/AM tuner.

A MOS FET and CG varicon are used to cope with high sensitivity and strong input distortion.

Two 4-element uniphase filters improve selectivity and distortion characteristics.

Output volume is mounted on the front of the multi-pass indicator and muting switch panel.
