The plinth is the main part of the turntable made by hand from several layers of carefully selected beech plywood – glued and then reinforced for greater rigidity. 

The top and bottom of the plinth are finished with 10mm thick aluminium plates followed by 3mm thick stainless-steel plates and 2mm layers of vibration damping material.

The tonearm is bolted to a POM cylinder rigidly attached to the plinth base.

This turntable is designed for a single tonearm.

Both the tonearm and the plinth are fully earthed.

12.5-inch unipivot tonearm

Materials used:

• headshell – microplasma-anodised aluminum/carbon fiber rigidly connected with the tonearm tube. (1/2 inch)
• arm – damped carbon fiber, aluminum, stainless steel
• 30AWG 5N PCOCC cabling. RCA wired directly to the cartridge.
• RCA connectors from the Australian company KLE Innovations
• The tonearm if fully adjustable for easy mounting of a variety of different cartridge types.

A plate handmade from 65mm thick Polyacetal (POM).

Available colour: black

Widely used by many leading turntable manufacturers, POM is an engineering thermoplastic that works perfectly as a turntable platter due to its vinyl-like properties.

Inverted, hydrodynamic bearing.

The main part is aluminium with 15mm stainless steel core rotating smoothly in a slide sleeve made of synthetic composites.

This solution is widely applied in the automotive and heavy industries as the component, unlike the commonly used bronze, is highly abrasion-resistant.

The platter is supported on a tungsten carbide ball (YG8) and a Teflon washer is fitted between the ball and the steel core for noise reduction. The POM bearing base is rigidly bolted to the inner layer of the plinth.

The bearing is manually polished for minimal friction.

A brushless DC motor is embedded in the plinth for minimizing vibrations transmitted to the platter and tonearm.

Thanks to the digital reflection sensor (2020)/ Signal from HALL sensor (2021)  and driver programmed by BennyAudio, the turntable speed adjusts automatically every few revolutions with an accuracy of 12 bits (4096 accuracy positions, an equivalent of 0.8 mV voltage change).  

Manual switch between 33.33 and 45 RPM with a push of an illuminated button also available during playback.

The speed deviation measured digitally (gyro – WOW 2sigma) during disc playback is +/- between 0.08 and 0.02%

Speed accuracy +/- 0.35%
