AMG 12J2 12inch Tonearm

“… truly ingenious bit of engineering…” – Michael Fremer

Bearing:

Dual-pivot design replaces the standard gimbaled bearing
Vertical bearing, similar to a technique used in the rotor heads of helicopters
Uses two .5mm thick “spring steel wires,” allowing fine azimuth adjustment while eliminating bearing play
Horizontal axle is a hardened tool steel, precision ground to a backlash-free git with a needle roller bearing
It is extremely precise, maintenance free, and never requires adjustment
