The FT-4 has an adjustable VTA base. If you are running the arm parallel to the platter, try raising or lowering the back of the arm a few degrees & see if there are positive results.
ALSO, be sure that the tracking force of the cartridge is set at or near the MAXIMUM recommended downforce -- probably about 2 grams.
BEST,
Joe
