Need help with anti-skating on Technics SL-1210GR

I believe that was stated well before Mijo chimed in by another member.
However it does seem that the consensus is that the run out groove method is valid if one does not have a true test lp, just that the OP was taking it too far not quite understanding the desired result.

I also highly recommend fine tuning the "by ear" method for day to day usage and tweaking of AS.

HI,
@mijostyn, hopeles I don’t think so.
I agree for checking HTA and overhang are correct before starting.
Mistracking can be heard without being severe.
Stylus profiles react differently to antiskate.
My point is that you do not need a gadget for adjusting antiskate and more is worse since is like applying more downforce.
Anybody has a tried method but I have seen a lot of cantilevers out of alignment beyond repair because of too much antiskate.

  Setting antiskate is not hard, nor an exact science. Because of the way antiskate changes as the tonearm moves closer to the end of a record there is no perfect number to set it at. Probably the biggest factor in antiskate is the tonearm bearing. Antiskate when measured with a proper antiskate gauge will show how good or poor a tonearm is designed and that is the reason why the same cartridge could have different antiskate settings in different tonearms.

  For a 9 inch tonearm, which you have, antiskate is about 7% at the beginning of the record and is about 10% at the second null point. This is just the physics of all of this, so don't get all twisted up in the numbers, it's not important to understand all of the science behind how these percentages were determined. 

  Your cartridge tracking force is 1.75 grams, set your antiskate at half that value .87 grams, which would be just below the 1 mark on your antiskate scale. Listen to an album. Do you hear any distortion in the right or left channels? If so add more antiskate if its left, less if its right. One important point, if you have to make an adjustment, make the move small, don't move the scale knob a full notch, just a tiny bit at a time. That's all there is to it. Your cartridge stylus will wear very evenly in the record groove. Now sit back and enjoy the music !!!
