LUXMAN WL515
¥ 44,000 (released in December 1968)
Commentary
FM/AM tuner incorporating FET and IC.
The front end is composed of a cascode amplifier circuit with FET to ensure high sensitivity and good SN.
An FET is also used for the frequency conversion stage, and the intermediate frequency amplification has five stages.
Equipped with a muting circuit.
