I'm more than quite sure that using a record without grooves is not the correct way to set antiskate and don't care what company or test record that suggests this. Why? because it is against the law of physics. A stylus travels in a groove and not on a flat surface. The stylus is traveling in between a groove touching the inner and outer walls of that groove. One side of the groove is rt channel and the other is the left channel. Setting on a record without grooves wiil not give a true and accurate measure of antiskate. "Think about it". I tend more to agree that our ears is the best way to set antiskate. Regards.
