Anti Skating adjustment

Hi, I was reading a response to a thread concerning anti skating adjustment. I was hoping someone could give me some advise. I just recently purchased a retipped Monster Cable Genesis 1000MkII while I send my Sigmas Genesis 2000MkII for a new stylus. Anyway, when lowering the new cartridge down on a protractor the cantilever deflects left. I have checked and recheck table balance and azimuth in the horizontal plane. All appears ok. The antiskating seems not to affect the deflection while lowering the cartridge onto the protractor. I have adjust antiskating with the Cardas "balancing plateau" track as well as a Hi Fi News test record. The antiskating adjustment does impact the tonearm movement when rotating a record but not when just lowering the cartridge onto the protractor. When lowering onto a record the deflection is still there but less noticable.
The retipping appears to maybe have affected the compliance of the cartridge. My turntable is an extensively modified AR ES-1 with all of George Merrill mods with an delrin/acrylic clamp and aluminum periphery ring, the tonearm is an Audioquest PT-9.

Imho abd experience the antiskating force is if not the same a little bit less than the vtf.

As the Vta the perfect way to get it right is begining from a standard point (arm paralel to the platter) and move up and down. With the A/S vegining from the vtf number and increase or decrease simply listening.

Forget to use the non-groove vinyl procedure because it is not right. It simply doesn't work

Nrenter,

1-. This cdr test is not valid because the skating force is applyed to the grooves, if you hae no grooves you have no information about skating force. Another reason is that for example SME arms always go to the center with this cdr test even if you add all the antiskating force to te arm.

2-. Probably it depends on the cartridge/arm relation BUT imho with all the cartridges i have had the a/s force was really really near to the vtf value. I think when this value is not near the vtf probably the problem is in the arm (age), the azimuth adjustment, etc...

Thanks for your inputs...

The fact is that as I said with ALL the SME models if you play a non groove vinyl always the arm goes to the center of the spindle so this cdr test is not valid, even it is not a clue. I also said that a/s force is added into the grooves and if you have no grooves you can't evaluate anything, this is the reason of the a/s tracks in some vinyls like Hifi news test record I have.

As Stringreen said before a/s is constantly changing but you should try to get the best sound possible, at least in my system if I change the a/s force I lose everything
