Back to the B60 : Alternative VTA adjuster
An alternative solution to easy and fine VTA adjustment is to tap a machine screw into a block of aluminium or bronze that slides under the arm lift cradle. I had one made years ago with a fine thread : 1/4 turn equated to 1 thou of an inch. You then unwind the screw until it just touches the underside of the arm lift cradle. From there you can easily remove it, adjust the screw up or down ( 1 turn is +-4 thou ) and then all you do is loosen the arm pillar screws, place the VTA measurer under the arm lift, and then drop the arm down to the new position. This little gizmo gives you complete control of fine VTA without the need for the B60.
My concern with most arms is that the arm pillars are secured by one or two grub screws - this is not particularly rigid. With the Helius tonearms the arm pillar is secured with a compression grip - this is far more rigid.
