Reference
The current hand-built Reference turntable employs a low-speed, recoil start synchronous motor on a single spring mounting driving the platter via a neoprene belt, thereby providing complete vibration insulation. The main bearing is manufactured from high-grade aluminium with two pressed fit P.T.F.E bushes at either end of the housing ensuring minimum contact with the bearing spindle, which it self comprises of a silver steel shaft and aluminium hub running on to a ceramic ball bearing. Platter speed is determined by the A.C mains frequency, which is effectively constant. Speed changing is accomplished by moving the drive belt from one motor pulley to the other.

The original Reference turntable featured a shaded-pole AC motor and had a variable speed range from 25rpm to a maximum of 80 rpm. Fitted with a one-piece removable arm board that ran the entire depth of the plinth. A Marine grade plywood plinth, hand painted black and finished off with polished aluminium trim and acrylic lid. A hand polished, cast aluminium platter fitted with three solid brass inertia weights. Provision was also provided for the sweep arm and stylus brush. Components were sub-contracted and manufactured by Almer Components, the same company David Gammon worked as chief engineer.
