Commentary
This is a separate stereo with a 3-point design consisting of a left and right speaker box and a center box.
Receiver section
The circuit configuration uses the complimentary service Darlington SEPP-ITL-OTL system using silicon power transistors, and the power transistors are protected by a pure electronic protector.
A transformer dedicated to transistor is used as the power transformer.
The FM tuner section is equipped with a double limiter circuit to enable playback with reduced noise.
The FM multi-circuit employs a switching system with excellent stability and reliability.
Player part
The record player uses a belt drive system with a synchronous motor.
Equipped with a Oatley tongue function, the arm returns automatically when the record performance ends.
In addition, an auto-cut system is adopted in which the arm returns and the power is turned off by operating the lever even in the middle of the music.
Speaker part
It is a 2-way configuration and equipped with newly developed 20 cm cone type woofer and 5 cm cone type tweeter.
Other
The free-style design allows you to position left and right speakers, amplifiers and players freely.
