Fidelity-Research FR-64/66 fonolab AMf-104 Tonearm VTA on the fly Adjustment Mechanism

A lot of vintage and current tonearm are not equipped with a VTA adjusting mechanism, by default, which creates certain difficulties when using them with modern quality cartridges. We have developed an original design of the VTA adjuster that fits perfectly into the various tonearm configurations.

The adjuster design includes extra-fine Mitutoyo micrometer head and micro bubble spirit level.

Features:
Fine spindle feeding of just 0.1mm/rev for extra-fine adjustment and positioning.
External dimensions are compatible with conventional 0.5mm pitch heads.

Technical Data:
Graduations: 0.002mm
Spindle pitch: 0.1mm
Spindle face: Spherical of SKS3 (more than HRC60), lapped surface
Scale surface: Hard-chrome plating

The VTA Adjustment Mechanism panel is made out of special aluminum alloy to absorb parasitic vibrations and has a characteristic silver color.
