You should NOT have the antiskate on or connected while making alignment adjustments. That is last step. In adjusting your anti skate, find a record with lots of dead wax near the label. Place stylus in the dead wax and watch how quickly or slowly the stylus moves toward the label/spindle. It should move gracefully, not too quickly and not too slowly. Usually the recommended position on the rod will coincide with your cartridge tracking force. The very outer rung is the most antiskating, while the rung nearest to the pivot is the least. So, you only have three options as there are only three rungs to hang the fishing line from.
Also, listen for distortion in right and left speaker...if your hearing it in the right, you have too much antiskating...if in left, you have too little...
