Transcriptors Hydraulic Reference turntable

Blast from the past in the 21st century... 

The hydraulic reference turntable was originally designed by David Gammon in 1964 and was the first turntable to employ the belt-drive system in Europe and to exposed all its mechanical components, a design approach which all turntable manufacturers adopt today. Amongst its many features were hydraulic speed control, vacuum operated reed switch and the latest in main bearing designs which incorporated a brand new engineering material, PTFE.

It has been used in many films and television ads including the classic 1972 film by the late Stanley Kubrick ‘A Clockwork Orange. The turntable also won a design award in the same year which was presented to David Gammon by late HRH Princess Margaret. It can also be found on display at the MoMa in New York and also Japan.
