Referring to LTA?... Best checked with something like Wally tractor tools. Simple way is make sure the arm is adjusted by checking as recommended by VPI..This is done before cart. mounting and is adjusted by the ring which sits at the base of the 10 arm..I dont know if the 10.5 does away with the ring..You should be able to call VPI with info. Basically you want to make sure the arm while unmounted, doesn't "tilt" to one side on the pivot. The Head shell should look perfectly straight and completely paralell to the platter surface. Then you can mount the cart, and go from there. But definately check the VTF first to see if that solves your jumpiness!
