Commentary
This is a belt drive player that thoroughly pursues usability.
The turntable is made of 30 cm aluminum alloy die-cast, and the dynamic balance is adjusted by precision balancing machine for each part to prevent harmful vibration.
The belt uses a precision processed polyurethane belt with thickness deviation reduced to micron units with special attention to aging of the belt and S / N ratio, and is equipped with a belt protection mechanism for further perfection.
Equipped with an overhang indicating device that serves as a sign lamp.
The optimum position of the needle tip can be determined simply by pulling out the lamp and aligning the needle tip to the center of the lamp.
A 4-pole hysteresis synchronous outer rotor motor is used for the drive part.
Direct reading scale allows for accurate needle pressure adjustment.
Arm can be moved up and down with the lever at hand.
The turntable shaft is polished with high precision by the centerless polishing method and the rolling method. The combination of the bearing with precision structure and the use of molybdenum disulfide grease with excellent lubricity makes it excellent in wow flutter characteristics and speed deviation characteristics.
Equipped with an inside force canceller.
Gold plating is applied to both terminals of head shell side and tone arm side to prevent contact failure.
Built-in insulator made of spongy special rubber, combined with the special support structure of the panel, prevents howling.
The dust cover uses a removable fleece top type.
Uses an oil-finished player case by Oceania cheeks natural wood.
The cartridge uses Technics 280C which is a MM type cartridge.
