Agnew Analog Type 631 Direct Drive Motor and Type 231 Control Module
The Agnew Analog Reference Instrument Type 631 is a high performance direct drive motor, designed for professional disk mastering lathes and turntables. It is usually positioned on the floor under the lathe or turntable, driving the platter directly by means of a long driveshaft, similar to the drive system of the Neumann VMS-70 and several other professional disk mastering systems.
