SANSUI SAX-150
¥ 31,900 (released in July 1969)
Commentary
A low-cost FM/AM receiver for personal use.
The front end of the tuner section uses an FET and a 3-row varicon.
In addition, the intermediate frequency amplifier stage is composed of three stages to achieve low distortion and high sensitivity.
The power amplifier section uses a quasi complimentary service circuit using silicon transistors.
Equipped with FM stereo indicator, FM autolinear scale, tape monitor switch, loudness control, etc.
