Phil:

With the VTAF I seem to have learned to operate the lift/lower mechanism of my Rega arm and my SME 3009 Series II unimproved arm without much movement of the arm during cueing. It will be interesting to see if other users will give us some input on this.

It does help to keep the guide assembly clearance fairly small to minimize wiggle allowed by the guide. On the other hand, the guide assembly should not be made tight, as getting it too tight can interfere with staying seated during VTA adjustment.

You are right that the small radial clearance between the VTAF Adjuster Screw and the VTAF Bronze Bushing does keep the arm mounting well centered. The .003 inch radial clearance between the adjuster screw and bronze bushing translates to a tracking error of .019 degrees, negligible when compared with the unavoidable tracking error of about 2.3 degrees characteristic of pivoted arms.

Can you comment on the sonic results you experienced when you incorprated the VTAF?

Yours, Pete, Pete Riggle Engineering and Audio
