+ AMG 12JT Turbo Tonearm

The 12JT Turbo expands upon AMG’s patented tonearm design with improved sound and functionality. The new larger bearing assembly houses both the unique vertical bearing and a larger horizontal axle, featuring dual micro-ball bearing assemblies for enhanced stability and reduced friction. All critical parameters of the 12JT Turbo are accomplished with calibrated locking thumbscrews for added rigidity and precise adjustment. The 12JT Turbo is available with the Viella V12 turntable as the AMG V12 Turbo package, and can be fitted to other turntables with our CIRCLE Linn-style or OVAL SME-style adaptors.
