The Hydraulic Reference Turntable is a design classic and has appeared in many films and TV commercials including the classic Stanley Kubrick film, A Clockwork Orange which David Gammon supplied to him from the film.
The hand-built turntable employs a low-speed, recoil start synchronous motor on a double-deck spring mounting driving the platter via a neoprene rubber belt, thereby providing complete vibration insulation. The main bearing incorporates a silicone fluid well rotating at the same speed as the platter, fine speed control being provided by a static vane immersed in the fluid. Platter speed is therefore determined by the A.C mains frequency, which is effectively constant, and the viscous fluid flow onto the vane, also effectively constant. Speed changing (45 r.p.m. and 33.3 r.p.m.) is accomplished by moving the drive belt from one motor pulley to the other and a neon-lit stroboscope is provided for accurate speed setting. In order to eliminate completely any mechanical shock to the turntable, on/off switching of the drive motor is accomplished by means of a reed switch. The Hydraulic Reference Turntable is also supplied sweep arm and stylus brush.
