Description
 
The solid-state FM multi-stereo tuner using a transistor.

The sensitivity improvement is aimed at with 4 new vista and the large-sized 4-unit variable condenser only for FM.

FM stereo monophonic automatic switching arrangement supervises FM stereophonic broadcast, and switches automatically.

The muting circuit is carried.

The noise filter and the automatic-frequency-control switch are carried.

The stability over heat is secured and the application-limits ambient temperature of 50 degrees C is attained.
