you are right, which is why I wrote

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.

Another probably important cause of uneven stylus wear is incorrect azimuth adjustment. In fact, any azimuth setting that does not set the stylus tip symmetrically in the groove with respect to its two contact patches is going to result in uneven stylus wear, eventually. This is the argument made by Korf for setting azimuth based on the fit of the stylus in the groove, not on electrical measurement of crosstalk, which will always have one setting the stylus at least slightly askew. |
Any deviance from straight is ’oppositely’ reflected in a mirror, this makes it very easy to see and get azimuth straight I use a 4" x 6" x 3mm mirror, https://www.amazon.com/dp/B07T31MRZ9?ref_=ppx_hzsearch_conn_dt_b_fed_asin_title_2&th=1
if you are a minimalist, this protractor is a mirror, same thickness as an LP. you need to make your own solution to measure overhang, and simply take it off the spindle, put it under the cartridge to set azimuth. https://www.amazon.com/Turntable-Cartridge-Stylus-Alignment-Protractor/dp/B005KR15HU
my latest find, a 30x magnified mirror with led light to keep below the cartridge to see the underside of the stylus https://www.amazon.com/dp/B0CLLZYBVK?ref_=ppx_hzsearch_conn_dt_b_fed_asin_title_1&th=1
I use this hudson hifi protractor, it has overhang measurement rings, and the other side is blank to watch and set anti-skate. I have a separage lp blank both sides for just anti-skate, will simply replace it after it get’s too scratched up from use. and I needed some stylus cleaning fluid, it comes with a very nice wooden handled brush, tall bristles to clean the stylus https://www.amazon.com/dp/B0CQC1TN25?ref_=ppx_hzsearch_conn_dt_b_fed_asin_title_2
finally, not for azimuth precision, I use the mirror, but to check if the flat part of the headshell/cartridge is parallel when in the groove (arm height afjustment), these small bubble levels, you leave them on, pick 6,7,8,9mm size, kit od 5

The problem is that some choose to use azimuth adjustment to optimize crosstalk measurements. When you do that, the stylus will only end up symmetrically placed in the groove if the cartridge was perfectly constructed internally, which the end user can never know for sure. If the coils are infinitesimally out of symmetry with respect to the magnets, then adjusting azimuth electronically will inevitably end up with azimuth set at something other than 90 degrees to the groove. That is the basis for Korf's recommendation to set azimuth geometrically. Your method is fine. |
