Commentary
This belt drive turntable was developed for Hi-Fi enthusiasts by CEC which was a manufacturer exclusively for phono motors.
The motor shaft and turntable periphery are driven by a single belt. The belt used in this case is an endless belt made of synthetic rubber.
The motor is a hysteresis synchronous motor newly developed by CEC.
This motor uses a rotor with strict dynamic balance, and achieves quiet rotation by special connection.
The turntable achieves vertical and horizontal runout of ± 0.05 mm or less by highly accurate intersection.
A gunmetal material is used for the bearing. The shaft is hardened special steel, polished and wrapped. The lower end of the shaft uses a one point support system with a steel ball and nylon thrust to obtain quiet rotation.
33 and 45 rotations can be switched by pressing the button.
When the power switch is turned ON, the neon lamp inside the push button lights up the push button.
The frame is made of light alloy with a reduced grey paint and a removable light alloy dress cover can be mounted above the motor pulleys.
