Specifications for ST-3 tuner:
An FM/AM tuner with a body of 315 mm width and 43.6 mm panel height incorporating Technics tuner technology.
The front end has a high sensitivity design that employs a 4-pole junction FET in the RF stage.
In addition, a ceramic filter is used in the IF stage to increase selectivity, and a high SN ratio is realized by wide-band quadrature detection.
The MPX for the MPX demodulation circuit, and demodulation is performed by double balanced and switching circuit to realize excellent stereo separation.
pped with an AFC (Automatic Frequency Control) circuit for more stable reception.
Equipped with a large flywheel for smooth tuning.
The guide with red LED is used for easy channel selection.
The AM tuner section has a complete IC structure and is designed to be resistant to spurious interference by combining it with a newly developed low-impedance ferrite antenna.
A direct connector is used for connection.
