About the TD 166 MkII

The Thorens TD 166 MK II is a vintage high-fidelity record player known for its robust build and precise engineering. Manufactured in Switzerland from 1976 to 1987, it features a semi-automatic operation with tonearm lift without feedback. The turntable uses a belt drive with two-stage gear reduction powered by a 16-pole synchronous AC motor controlled via mains frequency, offering mechanically switchable speeds of 33⅓ and 45 rpm. The platter is made of zinc injection moulding, weighs 2.7 kg, and measures 300 mm in diameter. It includes the TP 11 MK III or TP 21 tonearm and comes with an external 16 V power supply. The unit consumes 2.5 W of power and weighs approximately 8 kg. It is available in black or with optional wood veneer sides. The TD 166 MK II is praised for its low wow and flutter (≤ 0.05%), high rumble voltage spacing (> 70 dB), and stable motor control. It is considered a classic suspended sub-chassis deck with clear and stable sound reproduction. Restored units often come with a mounted Ortofon OM-10 cartridge with a new stylus for immediate playability. Dimensions are 430 x 150 x 360 mm (WxHxD) and 430 x 415 x 436 mm with the hood fully opened. The turntable is semi-automatic and does not have pitch control.
