Where does the 10% rule come from? I’ve heard it too, but I don’t know where or when. Let’s keep in mind also that there is no one value of AS that is correct at all times for all recordings. Ergo the analogy to aligning the suspension of an automobile is not compelling. Close is good enough and is likely to be exactly correct at certain moments.
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.

The 10% rule comes from the number of audiophiles who overthink even the simplest thing to the point it is complicated to incomprehensibility. Then after making something as simple as playing a record darn near impossible they wonder why more don't want to be audiophiles. The 10% rule also applies to the amount of time spent enjoying music vs measuring and calibrating. Also 10% is the correct amount to spend on your turntable, the other 90% of course being Wallytracker calibration jigs. |
@lewm , I believe the 10% figure came from a Shure study as representing the best average value. I have seen it mentioned in several places. You can probably talk to someone at Wally Tools about it. As far as I can tell it works fine. I set it at 10% and forget about it. I have watched the cantilever with a USB microscope and it does not deviate as it touches the record at three locations so it is certainly in the ballpark. |
The WallySkater is another great tool to have in your analog toolbox. in my analog system getting the antiskate set with the WallySkater made a very noticeable difference, for the good. the Wally tools might be to much money for some folks but I have $55K in my analog system so getting the best setup tools is important to me. I suggest that analog folks get a group together to buy some tools or be nice to someone who has one and borrow the setup tools. ‘Respectfully ‘Joenies |
