The
table is produce here by Artemis Labs in Southern California.
The development of this turntable stems from Mr. Frank Schroder years of
experience in the field of reproduction of vinyl records.
Some of the features that set this turntable apart from other designs past and
present are:
The 15Lbs platter anodized aircraft grade aluminum, turned to an extremely
tight tolerance in all directions.
The platter's thickness is maintain from center to the outer rim to avoid
variations in the mechanical impedance "seen" by the cartridge.
Platter damped with proprietary paper/felt inlay, allowing for the use of
different platter-record interfaces.
The massive, 3Lbs bearing is of the non-inverted type, utilizing a large
diameter, case hardened spindle and unusually long self lubricating phosphor
bronze bushings. The clearance is kept very small, but the defined surface
"roughness" of the spindle maintains an extremely stable oil film and creates
drag at the same time.
This turntable is driven by an extremely high quality Swiss DC motor for a
combination of high torque and smooth rotation, transfering power via 1/4
magnetic tape to the outer rim of the platter. Unlike other turntable
featuring a form of tape or belt drive, the tape is routed past a tensioning
lever/pulley to reduce both slippage to zero and minimize the side thrust on
the platter greatly. Residual motor vibrations cannot reach the platter
directly, but are absorbed by the suspended pulley.
To maintain absolute speed, there is no sensor based feedback loop, instead
the current drawn by the motor is monitored and kept steady through a clever
feed forward circuit designed by Mr. John Atwood. Wow and flutter is well
below audibility, certainly on par with the best direct drive designs.
The turntable can be set to both 33 rpm and 45 rpm, both individually
adjustable via set screws in the power supply.
