Grace G-747
Gyro Master Stereo Tonearm
Description
The Grace G-747 uses a lightweight, straight pipe design with all the robust characteristics of the 6mm diameter alloy pipe utilised on the earlier G-707 model retained, with a new process for additional rigidity.
We have developed a plug-in headshell which has succeeded in eliminating the dead mass found in many types of European headshell connectors.
The headshell itself is composed of specially hard-processed 2mm thick aluminium alloy.
The pivot points incorporate ultra-high precision micro bearings which have been finished to an extremely fine degree of tolerance.
The arm support system of the G-747 is by a proven gimbal support system, similar to the types utilised in aeronautical gyroscopic equipment - because it's vertical and horizontal parts all move under identical conditions, this system is ideal for stereo discs.
