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.

Yep, I just rechecked the bias with no VTF (balanced) and the A/S dial set to 0 produces no horizontal movement when "blowing" straight down on the headshell from above. Just a slight amount movement on the dial does start to move the tonearm away from the spindle. I set the VTF at 1.7grams with digital gauge and with A/S dial at zero there is still deflection easily seen. The sylus tip geometry is correct or at least looks straight down and vertical in relationship with the cantilever. It has to be the suspension!! I just bought this cartridge on Audiogon from an owner who had the retip service conducted by Soundsmith just recently. I would think that Peter at Soundsmith would check the suspension on arrival and before shipment out. I can't see how one would damage the suspension (previous owner) and not break the ruby cantilever. Oh well...my loss!
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
My anti skate force is about 1/10th of my VTF.

There is not a single "correct" anti-skate force. It is always an approximation that gives "better" performance given a constantly changing set of variables. Yes, listening is the best way to set anti-skate force, but it isn't the most helpful advice.

There are many "tricks" to help best determine this approximation. My personal favorite is steady the cartridge near the outer edge of a blank CD-R (similar to the blank LP method). I believe this is the method suggested by both Peter Ledermann and Frank Schroder (but my espresso hasn't kicked in, so my memory may be foggy).
Correcting an error in an earlier post, VTA is set with the top surface of the cartridge parallel to the platter.

Not the tonearm.
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...
