Commentary
AM/FM stereo tuner with improved reception accuracy by 2-meter wide dial mechanism.
FET is used in the front end to improve sensitivity and image ratio.
An IC and ceramic filter are used in the IF section to improve selectivity, capture ratio and S/N ratio and to obtain excellent interference rejection capability.
A ferrite bar antenna is mounted for reception of the AM part.
The combination of double-tuned IFT and silicon transistors enables Hi-Fi reception even in low-power regions.
The dial scale uses a wide linear type with evenly spaced FM graduations.
Combined with 2 meters, more accurate tuning is possible.
It has a multi-pass connector that can be connected to a stereo display or oscilloscope.
Equipped with separate output level controls for AM and FM.
It is also equipped with an FM muting switch and a Tape Rec terminal that allows direct recording to a tape deck.
