As the name proclaims, this was one of the first reference turntables (1963) with a pitch control as additional feature.
First by means of applied friction on top of the strobewheel, later through an under the platter affixed bassin filled with a thick viscose liquid, where a vane mounted on the chassis could be submerged in or lifted out in order to provide a 2% minus or plus speed.
After initial success and recognition production on a larger scale of the Hydraulic Reference was outsourced to the company of John Michell, who manufacture them according to conditions and terms stated in a manifest called the "Technical Agreement".
Later on, a German called, Jochen Räke, who used to work with Michell started his own turntable line called Transrotor, in which influences of the Transcriptor could still be recognized.
Our focus is on the Hydraulic Reference. For those who own one of these masterpieces we would like to give info concerning maintenance and repairs by means of manuals, pictures and tips
