A new way of adjusting anti skate!

I was looking at the Wallyskater, a $250 or so contraption used to set anti skate. https://www.wallyanalog.com/wallyskater  It is reputedly the most accurate way to set anti skate. Talking about fiddly. 

The appropriate figure is 9 to 11 percent of VTF. So if you are tracking at 2 grams you want 0.2 grams of anti skate.
My Charisma tracks at 2.4 grams so I should set the anti skate for 0.24 grams..................................Bright light!.
I readjusted the Syrinx PU3 to zero so that it was floating horizontally. I set up a digital VTF gauge on it's side at the edge of the platter so that the finger lift would be in the cross hairs, activated the anti skate and was easily able to adjust it to 0.24 grams. I started at 0.18 grams and just added a little more. Whatever you measure the anti skate from it has to be at the same radius as the stylus. If you do not have a finger lift at the right location you can tack a toothpick to the head shell and measure from that. As long as you have the whole affair balanced at zero you will be fine. Added cost $0.00 as long as you have a digital VTF gauge. 

I would not buy stock in Wallyskater.

That equation is bogus IF it defines “headshell angle”= headshell offset angle. In which case the skating force would be a constant which we know it is not. However, if headshell angle is defined as (tracking angle error + headshell offset angle), maybe it makes sense.  Gotta think about it a little more but that seems to work.

I was interested in your response re how you use the scale.  Dover explained your method, or as I understood his explanation of your method, as one in which you hold the scale vertically against the fingerlift on the headshell, with VTF set to zero and the arm floating.  From your last post, I gather that is not the case.  So what is your method, exactly?  Did you try anything akin to my idea?

Luisma, Depends upon how the AS device on your particular tonearm is graduated. I have often wondered about this.  For vintage Japanese tonearms and some modern ones that have magnetic antiskate devices, we typically see the dial marked in whole numbers: 1,2,3, etc. And the owners manual will often tell the user to set the AS device to a value equal to VTF.  This gives some of us the impression that AS should equal VTF.  But I wonder if in at least some cases, the manufacturer marks the dial as a guide only.  In other words, for dial marking of "2", you get an amount of AS that the manufacturer thinks is correct for VTF =2g.  But the AS may be much lower in gm of force than an actual 2g.  So when you say you are setting at 1.6 for a VTF = 1.4g, I don't think it necessarily means you are using 1.6g of AS.

trust the math and shoot for 9 to 11% of VTF

So basically for 1.4 gr of VTF use 0.14 gr of  "measured AS", towards the outer part of the disc of course

Use an amount that does not give you distortion in the R channel (too little) or in the L channel (too much) and does not result in a deviated cantilever after several hours of play.  And then, forgeddaboudit.

Agreed Lew, it is just a reference scale from the manufacturer

 

I am very impressed on my analog rig sound, the DL-301 although cheap it is incredibly good, rivals my digital, better soundstage
