Description
 
The arm-less player system of hall-motor adoption which all tone arms can attach.

MU-61 of a low-speed rotation DC servo hall motor is adopted as a phone motor.
S/N and the endurance are improved by adopting the brushless DC servo motor of the newly developed hall device using with a 10 times as much low-speed rotation as a turntable.

The velocity change organization of a pure electronic formula is carried, and also ±2% of velocity fine tune is also possible.

The gage which can deduce the mounting location of an arm easily is attached.

A mounting of 16 type arm is also possible by removing a book jacket.

The insulator by special rubber is attached for the measure against a howling.

There was an arm subboard as an option.
