Goldring G99 - Technical Specifications; Physical Dimensions

The hardened steel centre spindle runs in a sintered bronze bush with a special
thrust pad. The 4 pole constant velocity motor limits changes in turntable speed
to less than 1% for up to 13% change in line voltage. Rumble and hum are
negligible. Maximum wow and flutter is 0.2%. The turntable, which is die-cast
from zinc alloy, is non-magnetic and weighs 8 Ibs. A thick rubber mat is fitted.
Another feature is the push-button on-off switch which also engages and
disengages the drive. A neon pilot light gives the "99" an added refinement. The
switch circuit is entirely click suppressed. A vertical idler wheel transmits
drive from the motor to the underside of the turntable. The speed is infinitely
variable over the range 30/80 r.p.m. and from 15/18 r.p.m., and is altered by
means of a rotary knob which by a system of gears and levers moves the idler wheel
along a conical drive shaft of the motor. A neon-lit stroboscope is built into the
unit and very accurate speed settings are possible.
