Video Showing Setting Stylus Rake Angle Using a Digital USB Microscope
Set-Up Tips
Michael Fremer  |  Oct 23, 2017  |  44 comments
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.

Fozgometer Owner Alert !
Set-Up Tips

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.

Setting "Overhang" Using a "Double Null Point Grid" Type Alignment Gauge
Set-Up Tips

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.

Stylus Zenith Angle: A Heretofore Neglected Set-up Parameter Considered
Set-Up Tips
Michael Fremer  |  Feb 19, 2014  |  21 comments
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.
