VPI VTA Base question


Does anyone know how to tell the difference between VPI's current JMW VTA base, and the 12" Unipivot Base?  Something visual? Or measurements? 

I can't achieve the proper alignment with my 10" Fatboy arm and want to make sure I got the correct base.

Make sure that when you measure the S2P distance to hold the ruler level to the platter. Is there any opportunity to borrow a Dr. Feickert protractor (or similar) from your dealer to confirm the S2P distance?

,,just a silly question.....are you sure you have the pivot spike on the proper pivot.   I know If not careful, I can move my arm to another spot.   The correct spot has a metal insert and properly set up will allow the arm to tilt (azimuth) easily

Yeah, I must have pulled measurements and reset the arm on the pivot a hundred times over the past week.

I know what you mean stringreen, at first setting the arm down on the pivot felt a bit awkward compared to my older version. But you know when it’s on right, and it goes on easily now that I'm used to it.

 

 

My original (1995) jmw 10 has the arm pushed into the bell housing for a friction fit.  It can be less than seated and feel secure. The Fatboy looks similar.  Maybe get half a mm?
