Thorens TD318MKII Turntable

Description

The Thorens TD 318 MkII Turntable is a classic belt-drive record player produced by the Swiss audio manufacturer Thorens during the late 1980s and early 1990s. Part of the company’s respected TD-300 series, the TD 318 MkII was designed to offer audiophile-grade performance at a more accessible price than Thorens’ flagship models. Combining a suspended sub-chassis, precision belt-drive motor system, and a well-engineered tonearm, the turntable remains popular among vinyl enthusiasts and collectors of vintage hi-fi equipment.

At the heart of the TD 318 MkII is a belt-drive system powered by a low-voltage synchronous motor. The motor is controlled by a two-phase electronic generator that ensures stable rotation and precise speed control at both 33⅓ and 45 RPM. This design helps minimize vibration and speed variation, resulting in smooth playback with low wow and flutter. Measurements published for the model indicate wow and flutter of approximately 0.04% and rumble levels around –70 dB, figures that were competitive for high-quality consumer turntables of the era.

One of the defining features of the TD 318 MkII is its floating suspended chassis. In this design, the platter, bearing, and tonearm assembly sit on a sub-chassis that is isolated from the motor and outer plinth using spring suspension. The system reduces mechanical vibration and acoustic feedback from the environment, helping the cartridge track grooves more accurately. Thorens also incorporated specially designed leaf springs to further isolate the playing surface from motor noise and external vibration.

The turntable is typically fitted with the TP28 tonearm, a straight aluminum arm with precision gimbal bearings and a removable headshell. The bearings are designed for extremely low friction—less than 0.2 mN—allowing the cartridge to follow the groove with minimal resistance. Adjustable tracking force and anti-skating mechanisms make it compatible with a wide range of moving-magnet cartridges, giving users flexibility when selecting or upgrading their pickup.

Another practical feature is the semi-automatic operation with auto-stop. When a record reaches the end of the side, the tonearm automatically lifts, preventing unnecessary stylus wear while preserving the simplicity of a manual turntable during playback.

Listening impressions from vintage audio sources frequently highlight the turntable’s balanced and stable presentation. One review noted that the TD 318 delivered “a balanced and stable sound range” with “very satisfying stereo separation and depth of the acoustic image.”

Enthusiasts also appreciate its longevity and musicality. In a vintage audio comment, one user described it simply as a “solid, stable belt-drive turntable,” reflecting the reputation Thorens models have earned for durability and sound quality.

Because of its sturdy construction, upgrade potential, and classic suspended-chassis design, the TD 318 MkII remains highly regarded decades after its introduction. Many units are still in use today, often paired with modern cartridges and upgraded mats or belts. For listeners seeking the warm, engaging sound of vinyl combined with dependable engineering, the Thorens TD 318 MkII continues to be a respected entry point into the world of vintage audiophile turntables.
