@Yer Ol' Uncle D Anti-skate isn't adjustable. Before it started acting up, the tonearm did accidentally skate across a side of an album as I tried to lift it. Wasn’t jarring or anything but maybe that messed up the tracking force somehow.
Oh hey, that was you on Reddit. Possible you lost the stylus tip? The tonearm is dynamically balanced so I don’t know any other way it could have this kind of problem (provided it’s sitting on a nice flat surface).
