The Fluid Arm has been designed for use with cartridges, of not more than 16 grammes weight, tracking at not more than 2 grammes. The arm employs a uni-pivot working in a silicone damped well, so that the arm beam assembley relies for its lateral support, stabilty and resonant damping on the fluid surrounding the pivot. This results in a substantially fricition-free pivot of high stabilty.

An adjustable eccentric counterweight allows both lateral and longitudinal balancing of the arm. Fine control of longitudinal balancing to allow adjustment of the stylus tracking force withina fraction of a gramme is provided by a screwed counterweight.

Also provided is a bias compensating device so designed as to use a rolling motion. An adjustable bias weight operating through a pulley gives correct compensation as the stylus moves towards the centre of the record

A lifiting and positioning (or”cueing”) device is provided incorporating a hydraulic lowering handwheel which lowers thearm onto the record automatically , but which can be over-ridden when required for accurate positioning.
