Commentary
An AM/FM stereo receiver developed for high quality and high performance based on experience with the TK-40 and other products already on the market.
The circuit configuration of the amplifier is designed to reproduce without distortion by OTL of ITL and SEPP, and the frequency characteristic is improved especially by using silicon transistor.
The equalizer amplifier uses a direct-coupled amplifier circuit to reduce low-frequency losses caused by CR, etc.
Equipped with an automatic recovery type protection circuit to protect the power transistor.
The tuner section has a 3-row varicon, 5-stage IF amplification, and 4-stage limiter to obtain good sensitivity, S/N and selectivity.
In addition, it is equipped with an automatic switching device between mono and stereo. When stereo reception is received, it can be confirmed by the indicator.
An SCA filter is installed to prevent beat with SCA broadcasting.
