Sony PS-X30A (1979-1980)

A Japan-market turntable with precision speed control and electromagnetic braking, part of Sony's PS-X series

Overview

The Sony PS-X30A was built from 1979 to 1980 for the Japanese market. It sat lower in the PS-X lineup and came later, after the bestselling PS-X70. It has a diecast aluminium platter, a static balance tonearm, and speed control that was advanced for its class. The PS-X30 was the version sold outside Japan. It left out pitch control and the repeat function, and its platter was slightly lighter.

Design

The PS-X30A runs a BSL motor with Magnedisc and X'Tal Lock speed control, which keeps speed very stable. It also has electromagnetic braking, a low-capacitance output, and a long-span pivot aluminium tonearm. The enclosure is made of SBMC material, and the unit sits on gel-filled feet to cut vibration.

Context

The PS-X30A was a Japan-only follow-up to the popular PS-X70 line. It shares design language and technology with the higher-end models in the PS-X series, which includes the PS-X6, PS-X75, and the professional PS-8750.
