Commentary
An FM multi-stereo tuner developed with the aim of spreading FM multi-stereo to as many people as possible.
You can enjoy FM multi stereo broadcast transmission with TRIO's own circuit.
Equipped with an FM multi-stereo monitor unit, it is possible to distinguish between monaural broadcasting and multi stereo broadcast transmission with a switch.
Stable reception is possible with the tuning indicating meter and AFC (Automatic Frequency Stabilizer).
It also uses a 3-row varicon and a noise filter.
