Classic tonearm featuring a wooden arm tube and a thread and weight anti-skate system.

ADC model 40

Description

The Pritchard model 40 has a very low moment of inertia necessary for stable tracking at 3/4 gram.

To stabilise the centripetal force created by friction between the stylus and the record, a side thrust compensator is provided.

This results in an even pressure on both groove walls - essential for distortion-free stereo reproduction.

Precision, single ball bearings in gimbals reduce vertical and lateral friction to a negligible quantity.

Drag is further reduced by a unique wire guide so arranged that the ultra-fine lead wires twist along their own axis.
