I just played around with mine.. the cables are not the issue. Neither is the plastic sliding pad of the cue lever.
The tonearm "drifts" no matter what. (I set it high above the record, so that it doesn't touch it when lowered fully.. and it will drift outwards no matter whether it is all the way above the runout grove, or at the outer edge.. when I set it ON the record, then the drifting doesn't happen unless the record spins.. but I can see the outward force bending the needle in..)
Removing the antiskate made it much less pronounced, though..
However, if I play around with the vertical adjustment, again, with the tonearm "floating" above the record, I could eliminate the drifting.

Loosen the thumb screw and the tonearm fixture wiggles quite a bit (nothing precision about that, imo..)
It wiggles so much, that I can support it with one hand and adjust its ANGLE in a way that will cause the tonearm to NOT drift outward anymore.(By pushing the side opposite the thumbscrew "down" slightly)
As soon as I fasten the thumb screw, the opposite side gets LIFTED and the tonearm drifts outwards again.
my playing around revealed that I can get the tonearm to roughly stay in place no matter where above the record it was floating.. or even cause it to drift inward.. (without the antiskate pulling)
Maybe the tonearm base is not actually level and the fastened thumbscrew would actually fix it in a perfectly vertical position?
I'll need a tiny bubble scale to check the tonearm base..
It also doesn't matter where on the vertical axis I fasten the thumb screw, it always causes the "tilt" of the tonearm gimbal.. so it doesn't seem to be an indentation in the pillar underneath...
Maybe that's Brad's issue, too?
