Sony PS 1350
A belt-drive turntable system with precision engineering and low-vibration motor design
Overview
The Sony PS-1350 is a stereo turntable system manufactured by Sony. It features a 30 cm aluminum die-cast platter driven by a 4-pole synchronous motor via a belt drive system, supporting 33 1/3 and 45 rpm playback. The turntable includes a static balance S-shaped tone arm and comes with an MM-type cartridge equipped with a 0.5 mil diamond needle. Designed for stability and accuracy, it incorporates a high-precision urethane belt, a rubber sheet to suppress record vibrations, and a removable acrylic dust cover. The system is built with a focus on minimizing vibration and maximizing tracking precision.

Design
The PS-1350 uses a 4-pole synchronous motor developed exclusively for low vibration. It features a high-precision urethane belt with both sides polished and a rubber sheet designed to suppress harmful record vibrations while ensuring secure fit. The static balanced universal tone arm includes a precision pivot bearing for increased sensitivity, with a damper-supported section for vibration resistance. The turntable is equipped with a built-in strobe/scaler for speed verification, a low-capacity output cord to reduce high-frequency loss, and a height-adjustable insulator. A removable acrylic dust cover is included.
