Make sure your table is perfectly level. Then check the set up of the arm. If there is too much overhang the skating force will increase. I have also seen a broken stylus do this before. Bad diamond. It just fractured. It sounded surprisingly normal! I suspect your tonearm is normal. I am also assuming that the anti skate weight and mechanism is normal. Blank records get you in the ballpark but you need a test record to set anti skate properly.
