AMG 9W2 Tonearm 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.
