I finally get it!

I had a long  discourse with VPI after I bought my new Classic 3 Sig SE years ago. The subject was that the S2P distance was off. After over one year of trying to get this resolved, I still received my tt back with this distance 1 mm (long).

I always wondered why there was no forthcoming measurement of the S2P distance. After all, VPI is know to have customers DIY their own tts, based on VPI's own products.

So, VPI offers their set-up jig with new tts. They don't offer any specific measurements for S2P. Someone had to ask on their forums in order to find out. Why?

I now know why. Because, their manufacturing was/is not very precise. So, if their S2P distance was off when the tt left their shop, their own jig (provided) would still keep the S2P distance in a (good enough) range. 

Nice try/trick.

@bdp24 ,

I hear you brother 

I became a believer years ago, when I first made a wire loom for my ET arm. It was a revalation.

@phoenixengnr From the table on the turntablebasics website,for a 230 mm EL the optimum OH is 18.14, and the angle is 24.083 deg:for a 229 mm EL the optimum OH is 18,05 and the angle is 23.972 deg.This kind of difference is hard to measure, thus not a drama.
 

The 1 mm error in 230 mm is 0.4%. I can't name manufacturers, but I recall both Fremer and Dudley mentioning this kind of error more than once.

Please read the references.

IME that is a serious oversite. High end analog is not at all forgiving to issues like this. Glad you got it worked out Slaw.
