Gimbal Bearing Tonearm

review this tonearm (1 review)

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

ADC model 40


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.


Arm length: 10 5/8" overall

Pivot to stylus tip: 9"

Rear overhang: 1 3/4"

Fundamental resonance: 6 cycles/sec

System tracks at 3/4g
