Kit to use a double string on a GD3 Turntable.
The application of 2 strings provides a greater torque and provides
a more stable sound image.
For this purpose the pulley has to be adjusted and the turntable
only makes 33⅓ revolutions per minute.
In combination with an ALE, 45 rpm is also possible.
When using a double string, 78 rpm is not possible.
The delivery includes a set of strings and a pulley.
