item description

Turntable
- Chassis piano-lacquered dark grey
- A quiet running AC motor with a two-step pulley drives the hub and platter via a flat-ground belt.
- The medium density fibre plinth stands on three height-adjustable rubber-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 cork mat (a standard felt mat is supplied also) and a screw-down record clamp.
- The platter's low-tolerance chrome-plated stainless-steel axle runs on a Teflon bearing plate in a sintered bronze bearing housing.
- 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.


Tonearm 9cc
- As an optional extra, the turntable is supplied with Ortofon 2M Red MM-cartridge fitted.
- The headshell and armtube are fashioned from a single piece of carbon-fibre.
- Conical armtube avoids standing wave reflections.
- Inverted tonearm bearing comprises four hardened stainless tips in ABEC7 spec ballraces.
- 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 11 - 15g, 8 - 11g or 5 - 8g 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.
