iirc, the weak point is the tp-16 arm. On many of those circular metal ring type mounts for the arm bearings, the given metals relax over time and get out of round. Depending on the design the bearings can and usually do tighten or loosen up.
the removable wand is a weak point, both electrically and mechanically. oops, wring arm, I think. regardless, removable head shells are a weak point.
Upgrading the arm can be one of the ways to go.
However beware arm mass and effective length of the given chosen replacement. It must fit in for the original in a fairly narrow range of mass and effective length.
the length issue is due to the arm base/board being very small, and no option for mounting outside of that small footprint is really viable.. and the mass being an issue as the suspension of the td-160 was not really designed to be messed with due to different arms in use.
