Commentary
An FM tuner that combines all transistors into a compact size.
The front end is an all-transistor type that does not use vacuum tubes or new vistas.
As a result, the circuit does not generate heat like a vacuum tube and is stable.
Selectivity is improved by the combination of all-transistor-type 3-row varicon front end and IF5-stage amplification.
In addition, the noise limiter, which cuts out external noise, is a full-scale one with three stages.
Equipped with TRIO's own FM mono to stereo automatic switching device, it automatically receives stereo broadcast transmission.
In addition, an FM stereo indicator lamp is installed to indicate whether the broadcast being received is stereo or not.
