Sony PS-2300A (c. 1972)
A refined, belt-driven turntable based on the PS-2300, featuring a precision motor, low-vibration design, and universal tonearm.
Overview
The Sony PS-2300A is a belt-drive turntable introduced around 1972 as a cosmetic "dress-up" version of the PS-2300, emphasizing basic performance with enhanced mechanical design. Manufactured by Sony, it features a dedicated 4-pole hysteresis synchronous motor engineered for minimal vibration and paired with a high-precision polyurethane belt. The turntable uses an oilless metal bearing that requires no lubrication, contributing to long-term reliability. It includes a static balanced universal tonearm with a built-in lifter and supports standard headshells for broad cartridge compatibility. The detachable acrylic dust cover has a felt/fleece top surface, and the unit comes with a 45 rpm adapter.

Design
The PS-2300A features a dedicated hysteresis synchronous motor designed for minimal vibration and uses a high-precision polyurethane belt for consistent speed. Its oilless metal bearing requires no lubrication, enhancing long-term reliability. The turntable is equipped with a newly developed universal tonearm that includes a built-in lifter and supports standard (international) headshells, allowing for cartridge interchangeability. Low-capacitance output cables reduce high-frequency loss, and the detachable acrylic dust cover has a felt/fleece top surface for added protection.
Context
The PS-2300A is an enhanced variant of the Sony PS-2300 turntable, marketed as a cosmetic upgrade while retaining its core performance features. It is listed among Sony's "Legendary Products" alongside models such as the PS-X75 Biotracer and PS-8750.
