Commentary
This FM stereo tuner is not a technology for technology but an FM stereo tuner developed with the aim of approaching human infection.
The front-end section uses newly developed technologies such as a 7-series varicon, a dual-gate MOS FET push-pull RF amplifier circuit, a phased keyed AGC, and a double-balanced mixer to achieve high sensitivity, low distortion, and low noise as well as excellent selectivity and interference rejection.
The IF stage is equipped with two circuits, one for strong electric field (WIDE) and the other for weak electric field (NARROW), and has a simple design with subcircuits removed from the main path.
Equipped with 3 meters of touch sensor, servo lock mechanism, tuning / signal / multi-path.
