+ AMG 9W2 Tonearm

Based on the award winning AMG 12J2 12” tonearm, the new  9W2 9” tonearm use a scaled version of our patented dual-pivot bearing. The vertical bearing, similar to a technique used in helicopter rotors, utilizes 2 steel wires that allow fine azimuth adjustment while eliminating bearing play. The horizontal axle is hardened tool steel needle roller bearing. The aircraft grade aluminum armwand is anodized for resonance control. Identical to the 12J2, the new 9” tonearm’s internal wiring is multiple stranded high-purity copper, and features magnetic anti-skate and precision locking VTA adjustment. The 9W2, with a pivot to spindle distance of 211mm, is designed for the Linn LP-12, as the second arm on an AMG Viella 12 using the TWIN armboard with OVAL SME mount adapter, or other turntables that accommodate this length.



The 9W2 tonearm uses the same bearing technology as, the 12J2 (shown).
