Savor.
Right. Because the solution VPI came up with is inconsistent. Now again I never used one of these so not really sure if it works the way I’m thinking. But it looks like as the arm moves inward it changes the twist in the wire. Not even sure which way the darn thing twists! But now you know what is going on you can figure it out and fix it.
Yeah it is crazy. Actually the anti-skate problem does come up, at least often enough a guy like me who’s never even seen a VPI knows all about it. Usually though people don’t seem to notice until its off enough to cause actual mistracking and breakup. The level of anti-skate error you are noticing, slight center image shift, is actually quite small.
You might be able to tweak it out with patient persistent wire twisting. Or get it down to where its not worth the bother. One thing you may notice, the center image shift is but the most obvious sign. Because if the center image is shifting then really the whole stage is a bit weak compared to what it could be. Fine tuning and tweaks is where its at with vinyl. Its the difference between being a lot better than digital and OMG why does anyone ever even want to listen to anything else!?!
It would be real simple to make your own anti-skate, if it weren’t for your JMW-9 arm being uni-pivot. It can still be done, just a little trickier to implement. Can you use the VPI option?
Oh my god. @millercarbon, you are completely right.Heh.
Savor.
I have noticed that when the last track of the record is playing, the right channel shift is noticeably less pronounced.

Though has anyone else mentioned this problem? It’s so clearly obvious that anyone with a Scout or similarly built turntable should be reporting it? How the heck can you correct for something like this. Crazy,
