About the SP-10 MK3

The Technics SP10 MK3 is a high-end professional direct-drive turntable motor unit produced from 1982 to 1986 in Japan. It features a brushless DC motor with electronic rectification and a quartz-controlled phase-locked servo circuit, delivering exceptional speed stability and torque. The turntable has a heavy 10kg two-ply die-cast aluminum platter with a 15mm thick copper alloy core, providing high inertia for stable rotation. It supports speeds of 33 1/3, 45, and 78.26 rpm with a pitch control range of ±9.9%. The starting torque is 16 kg-cm, enabling rapid start-up in 0.25 seconds and braking in 0.3 seconds. Speed fluctuation under load is effectively zero up to 10 kg-cm. It achieves wow and flutter of 0.015% WRMS (JIS C5521) and rumble noise ratio of -92 dB (IEC 98A weighted). The unit weighs 18 kg and measures 369 x 113 x 369 mm. It was designed for professional studio use, including LP mastering, and is regarded as one of the most accurate and stable turntables ever made. The SP10 MK3 requires an external control unit and does not include a tonearm or cartridge. It is highly regarded for its robust build, precision engineering, and remains a reference in analog playback systems.
