Many characteristics were improved by adopting the highest-class dual gate MOS FET and a frequency straight line type Joint 4 variable condenser as FM front end part, and the degree of selection and the capture ratio are improved by using three ceramics filters for IF magnification stage.
Moreover, low distortion and FM reception of low noise are enabled with combination with four ICs.
IC and the 15kHz low pass filter, and the low noise silicon transistor were carried in the MPX circuit, and the stable stereo effect has been acquired.
Moreover, FM muting circuit is carried.

The triple variable condenser and the ceramics filter are adopted as AM tuner part.

The preamplifier part considered it as the whole page direct connection circuit using a silicon transistor, and has improved the frequency response.
Furthermore, NF type bus treble-control circuit can be adjusted at a 2dB step.

A power amplifier part adopts an ITL-OTL-OCL circuit, and is improving efficiency.

The internal organs of a power supply stabilization circuit, or the transistor / speaker protection circuit are carried out.

Preset volume is carried.
