Luxman PD272 (1977)
A direct-drive turntable released in December 1977, featuring a brushless slotless DC servo motor and precision static-balance tone arm.
Overview
The Luxman PD272 is a high-fidelity turntable released in December 1977. It builds on the design lineage of the PD121 and PD131 models, incorporating a direct drive system with a brushless and slotless flat DC servo motor to minimize rotational irregularities. The turntable uses a 30 cm aluminum die-cast platter weighing 1.8 kg, designed for high rotational stability. It supports 33 1/3 and 45 rpm speeds with independent ±4% adjustment for each, and achieves a wow flutter of 0.03% or less (WRMS). The signal-to-noise ratio is rated at 60 dB (IEC-B).
It features a straight-type static balance tone arm with an effective length of 240 mm, overhang of 15 mm, and adjustable needle pressure from 0 to 3 g. The arm is compatible with cartridges weighing between 4 g and 11 g and includes height adjustment ranging from 13.5 mm to 20.5 mm. Operation is simplified via a 1-lever, 2-action switch that controls both power and speed selection.

Design
The PD272 uses a brushless and slotless flat DC servo motor, eliminating magnetic rotation unevenness caused by motor slots. This is paired with a high-inertia die-cast aluminum platter, concentrating mass on the outer circumference for stable rotation. The straight static-balance tone arm features a double-pipe bearing structure to prevent resonance and integrates the cartridge shell for high rigidity and improved trackability. The dust cover is made of bonded acrylic to resist howling and adds weight to the chassis when closed. A specially treated flutter mat made of high-density rubber ensures secure record adhesion and effective damping. The power supply uses an ultra-thin OI core transformer with minimal leakage flux to enhance rotational stability and signal-to-noise ratio. The turntable includes a mirror reflection strobe scope, an oil-damped arm lifter, a thread-hooking lever type inside four-scan cellar, and a 1-lever, 2-action switch for power and speed control.
Context
The Luxman PD272 is a direct descendant of the PD121 and PD131 turntable models, continuing their engineering philosophy. While the PD-444 and PD-555 are noted as premium Luxman turntables with heavy platters and advanced tonearms, no explicit relationship to the PD272 is documented.
