For sale a Victor / JVC TT-71 Quartz Lock direct drive turntable in very good condition. Turntable works properly and keeps speed well. It comes with Rega R200 tonearm and working Audio Technica cartridge.
Description (from website):
This is a Quartz lock servo DD turntable with advanced machine technology.
The drive motor uses the same DC brushless motor as the TT-81 type. Smooth and accurate rotation is achieved by the combination of a strong torque of 1kg-cm or more and a high-precision all-round integral detection FG servo system.
The phase comparator circuit uses a sample-and-hold type circuit with good response to improve the accuracy of the speed control signal.
350kg-cm in order to deal with short period rotation unevenness and instantaneous load fluctuation which cannot be covered by quartz lock.2Heavy duty turntable with inertial mass is adopted.
A touch sensor system is used for speed switching and stop.
Equipped with an electromagnetic quick brake mechanism.
