AM / FM Stereo Tuner
4-gang tuning condenser and dual gate 4-pole FET's in FM front end
Ceramic filters and two ICs consist of differential amplifier limiter in FM IF circuit
Linear, wide-scale dial, and two tuning meters, and AFC on/off switch, and FM muting circuit
RF amplification, double stage AGC and ceramic filter for low distortion and high AM sensitivity and for normal operation opposing strong signals
High-blend switch and manual FM/FM-stereo switch for improving Signal-to-Noise Ratio at weak FM stereo signal
Output terminal for future FM 4-channel broadcasting
