A direct-drive turntable from Sony's 1970s audio lineup, featuring a linear slotless motor and precision Magne-disk speed control.
Overview
The Sony PS-X3 is a manual turntable produced during Sony's high-fidelity audio era. It uses a direct drive system with a newly developed linear slotless motor and a 32 cm aluminum die-cast platter for stable rotation. Speed accuracy is maintained via a crystal lock system using Magne-disk rotational frequency detection, a technology derived from Sony's precision instruments. The turntable includes a static balance S-shaped tone arm with adjustable height and comes with an aluminum die-cast head shell and removable acrylic dust cover.

Design
The PS-X3 uses a direct drive system powered by a linear slotless motor that turns the 32 cm aluminum die-cast turntable directly. Speed control is managed by a Magne-disk rotational speed detection system, based on Sony’s Magne-scale technology. It features a peripheral strobe with a stroboscopic illumination prism, an oil dump type arm lifter, and an adjustable tone arm height mechanism that allows 6 mm of vertical adjustment. The tone arm includes a rotatable arm rest for easier needle pressure setup. The head shell is aluminum die-cast with a slide bar, and the cartridge incorporates a conical damper and pole piece blocks made of resin mixed with carbon fiber. The cabinet is an integrated SBMC structure, and the unit includes two replacement shell stands and a low-capacity phono cord.
