The armboard, platter and plinth should all be located on absolutely parallel planes and if they’re not, there will be an issue. In mijostyn’s case, he’s mentioned several times that his pickup arm azimuth changes when VTA changes. That can be explained by a misalignment between arm/platter/plinth.
... the devise that has to be level to prevent skating forces is the tonearm. So the best place to put your bubble level is on the tonearm board or plinth right at the base of the tonearm. If the platter is a tiny bit off it won’t matter.Even a level pivoted pickup arm will generate skating force provided the arm has overhang, which almost all do.
