Goatwuss, hopefully this note finds you well and with resolution to you problem.
I recently found a fix to this problem on my TT from an unexpected source. I run a Goldmund Studio with an SME V, a mod, in place of the std. T3 arm. In short, I suspect the supplied SME protractor from my early vintage arm to be incorrect somewhat. Basically a friend loaned me his SME 30/2 with Phanton arm for a month and I noticed how even with a naked eye his arm had a more aggressive alingment angle compared to my setup. So I copied and applied that setup to mine and the problem was gone! Secondly, not sure if you arm is one of those where the tonearm cable comes out on top of the "hub", those are usually "coiled" and the cable gets a bit of tension towards the inner tracks, and it adds to your Anti-Skate as it tries to "uncoil" itself. Not sure if this makes sense to you? Goodluck in your quest!
