VPI super platter upgrade with JMW 12.5

Problem: I've recently upgraded by TNT 4 with a new Super Plater. Everything's running fine other than my 12.5 arm is more-or-less at the extent of its elevation, which has made it feel a tad wobbly with just minimal thread holding everything in place.

With the thicker platter (I'm guessing 5mm) obviously the arm has to be elevated more than it was in its original set-up

I've managed to achieved a level arm, but my ZYX prefers a slight lift.

Has anybody experienced (and solved) this problem?

Thought there may be some sort of 'spacer' that I can add between the TT base and arm, but seen nothing around.

I'm sure I've installed the platter correctly - not much to get wrong here.

Thanks for reading.

Rennie, I ran into this same problem when upgrading my VPI TNT 3.5 a number of years ago. What Markd51 says is accurate. VPI went to a taller arm board when they introduced the TNT 6 version of the turntable about five years ago. With the TNT 6 version of the 'table, VPI went to the taller all-acrylic platters. The new Super Platters are the same height as the all-acrylic platters (i.e., taller than the platters on the Mk. 5 and earlier versions of the TNT).

At the time I upgraded my turntable (about four years ago), VPI was making an acrylic spacer to elevate the height of the arm boards. The spacer is designed to sit in the arm board cutout with the arm board sitting on top of the spacer. The result if to elevate the height of the tonearm by a half-inch or so. I am hoping you will find that VPI still stocks the arm board spacers.

Good luck!
