Well, that’s a clickbait headline for sure, but unlike most it’s probably true, especially if you’ve taken my word on this.

Skating, a pivoted tonearm’s tendency to “skate” towards the record center is real, is not created by “centripetal force” and is not best ignored because compensating for it somehow worsens sonic performance.

If you do not apply some kind of skating counterforce, the stylus will ride the inner groove throughout the record side, producing uneven record and stylus wear. And it can’t possibly improve record playback sound.

WAM Engineering's new universal WallyTractor is now available from the newly formed company, a partnership between the late Wally Malewicz's son Andrzej, himself a mechanical engineer and Wally's former production assistant J.R. Boisclair. They've just launched the Wallyanalog website where you will find complete details of the new $395 universal WallyTractor and the available services the Santa Rosa, CA based company provides.

At the San Francisco Audiophile Society meeting late September where I appeared and played records for a few hours (and had a blast), J.R. Boisclair was selling what remained of Wally Malewicz's "Wally Tools".

This video shows you how to use a digital USB microscope to set stylus rake angle (SRA) to 92 degrees, which is considered to be the best angle to start with, followed by adjusting "by ear". Why 92 degrees? It's all explained in an article you can download as a PDF file at this analogPlanet.com link.

This drawing explains tone arm basic geometry. Thanks to Wally Malewicz for providing it. So let’s go through it together.

If you own and use a Fozgometer to set azimuth you must calibrate the unit or your results will not be accurate. I had stopped using my Fozgometer and instead was setting azimuth using a digital oscilloscope, which is 100% accurate and also gives you precise crosstalk voltages.

In the Rocky Mountain Wrap Up I wrote about the UNI-DIN curve versus Löfgren but a picture (or a graph in this case prepared by WAM Engineering's Wally Malewicz) is worth a 1000 words.

How did this one get neglected? Take a look at the photo supplied by WAM engineering. It shows a stylus in a cantilever. Notice it has been affixed into the cantilever at an angle instead of being parallel to the cantilever. If you use the cantilever to set the zenith angle on this cartridge, which is what I and everyone else recommends, the stylus will not be tangential to the grooves at the null points though it might accidentally be so somewhere else.

The animated graphic here is taken from the DVD "21st Century Vinyl: Michael Fremer's Practical Guide to Turntable Set-up". The gauge is similar to the kind supplied by Pro-Ject and other turntable manufacturers. It's accuracy is predicated upon the correct pivot-to-spindle for the particular tonearm.

Back in the fall of 2008 I attend an audio show in Trondheim, Norway where I presented two turntable set-up seminars. The show organizers procured for me a Tri-Planar tonearm mounted on a turntable, the brand of which I forget.

To continue the discussion of whether or not using a USB microscope to set stylus rake angle is a good or bad idea, please look at the drawing accompanying this post.

In Part 1 we explained the importance of proper azimuth setup. Now, on to how to achieve it! While using a digital oscilloscope is the most accurate method, it also requires you to spend hundreds of dollars to buy one and then you have to learn how to use it. That's not really necessary for most analog devotees, and so we're not going to go into the details here. If you insist, you'll have to buy one and figure it out using the methodology that will be described, which is generally applicable to whichever way you choose to go.

"Azimuth" is generally defined as the perpendicularity of the cantilever to the record surface. Some tonearms, including most (but not all) gimbaled tonearms (ones with fixed bearings like Rega and fixed head shell SME's don't allow you to adjust that parameter. You are at the mercy of the cartridge manufacturer, but that doesn't mean you shouldn't check your cartridge's performance even if you can't adjust it.
