TRIO FX-80D
¥ 33,500 (released in 1966)
Commentary
A top-of-the-line FM tuner that combines Trio's solid state and FM technologies.
In order to greatly increase the number of FM stations, we have adopted a four row variable capacitor in the front end section.
As a result, various characteristics are improved.
The IFT circuit uses 5-stage amplification and 4-stage limiter to suppress external noise.
It is equipped with a muting circuit to prevent harsh noise during FM tuning.
Equipped with a pure electronic FM mono-stereo switching device.
Equipped with an automatic device and a stereo / mono lamp that turns on the dial face.
An SCA filter is built in to prevent interference of SCA broadcasts.
