Product information

 

Turntable 

 

A quiet running AC motor with a two-step pulley drives the acrylic hub and platter via a flat-ground belt. 

 

The medium density fibre plinth stands on three height-adjustable Sorbothane

®

-damped aluminium cones. 

 

The motor is decoupled from the plinth to reduce vibration transmission. 

 

The resonance-optimised platter is a sandwich construction utilising the hub, an medium density fibre 

platter, a 4mm thick flat-ground layer of vinyl and a brass record puck. 

 

The inverted bearing uses a stainless-steel axle carrying a ceramic ball on which the ceramic bearing plate runs. 

 

Electronic speed change for 33/45 r.p.m.. Switching to 78 r.p.m. is done manually.  

 

Central metal block optimises centre of gravity and damps main bearing. 

 

Connection to the phono input of the amplifier can be made with connecting cables of your taste through the 
gold plated phono sockets and earth screw. A standard cable is provided. 

 

External power supply avoids potential electro-mechanical interference.

Conical carbon-fibre armtube avoids standing wave reflections. 

 

Low mass aluminium headshell securely glued to armtube. 

 

The inverted bearings consist of four hardened stainless steel points bearing in sapphire cushes. 

 

Rings provide very solid arm bearing housings. The outside ring is open to avoid resonances. 

 

Design of counterweight effectively counteracts unwanted resonances.  

 

The counterweight supplied is suitable for cartridges weighing between 6 - 10g. Alternative counterweights for 

cartridges weighing between 10 - 15g, 9 - 11g or 4 - 6g are available as an accessory part. 

 

Counterweight shaft lowered to record level reduces cantilever forces and dynamic wow when playing 
warped records. 

 

Solid armbase permits accurate height adjustment of armtube and VTA (vertical tracing angle). 

 

Single-screw fixing of armtube allows rotation for easy adjustment of needle azimuth despite fixed headshell. 

 

Silicone-damped armlift can be adjusted to suit working height of the arm. 

 

The internal wiring consists of flexible high-purity copper from the headshell right through to the gold-plated 
phono sockets. 

Dimensions W x H x D: 385 x 170 x 330mm. Dust cover Cover it optional. W x H x D: 460 x 225 x 365mm.
