Commentary
FM/AM tuner that is paired with SB 210.
A 3-row varicon is used for the front end part to improve sensitivity.
A highly integrated IC is used for the intermediate frequency amplifier.
A PLL IC is used in the stereo demodulation circuit to ensure stable stereo separation.
Uses a side terminal structure for easy cord connection.
Equipped with an FM muting switch.
It uses a 2-meter system and is equipped with a signal meter for measuring signal strength and a tuning meter for selecting the minimum distortion point.
Equipped with panel handle.
