Step by Step How to Use a Digital Multimeter / Oscilloscope for Azimuth Adjustments

Mijostyn, You wrote, "all you have to do is get a test record with a test tone equal in both channels, reverse the leads on one channel at the cartridge, put your meter on AC and adjust the azimuth for the lowest voltage."
Obviously, your method is much simpler than mine, too simple in fact.  First, any channel imbalance will dominate any crosstalk.  So essentially you will be correcting for channel imbalance. Using azimuth to correct for channel imbalance is NOT good, because azimuth has little effect on that parameter, and one ends up with very extreme azimuth angles. (I tried this once just to verify the fact that azimuth does not much effect balance, using my Triplanar.  The cartridge ended up about 20-30 degrees off top dead center to achieve a 1.5 or 2db change in balance.) Second, as you say, your method addresses only one of two possible goals of electrical setting, the choice to equalize crosstalk, L channel into R and R channel into L. It wouldn't work for the goal of "least" crosstalk, where there is no thought of equalizing crosstalk. (I hope that makes sense; think about it.)  In all my experience, if you aim for equal crosstalk (L into R = R into L), that setting is not the same setting as for lowest amount of crosstalk, where equality between the two sides is ignored.  There are whole white papers written by guys who know more than we do about why one or the other goal is "best".  Anyway, I am now a follower of Korf's method; I have ceased even to measure electrical crosstalk.

@lewm  is dead right.

According to Peter Lederman, matching electronically usually means equalizing channel separation, which is a bad idea which can lead to a poor adjustment. So if you have a high end cartridge, with natural channel separation of say 37dB in one channel and 43dB in the other, you have to cant the stylus at a ridiculous angle to equalize.

Ask me how I know. My higher end Koetsu must have been at 10 degrees to equalize channel separation. Sounded terrible. Set optically and then by ear, and the cartridge sounds sublime. And it scarcely wears at all.

Assuming I've interpreted Lederman correctly and my observations are not too subjective. Anyway, YMMV.

Interesting report. My experience was also with a Koetsu, an Urushi. What I reported above was what I observed when I used azimuth to alter channel balance, just to see if what others described was true, that azimuth has very little effect on balance for a very large change in azimuth. It was true; for a less than 2db change in balance, the azimuth needed to be 20-30 degrees offcenter.  But also when I next set the Urushi for equal crosstalk, the cartridge ended up at least 5-10 degrees off top dead center. Being a slave to numbers, I listened to it that way for some time. It never sounded as good as an Urushi should sound (in my Triplanar). When I finally readjusted azimuth so as to approximate a 90 degree orientation, regardless of numbers, it sounded much much better. The obvious problem is that equal crosstalk seems to be a good idea, but if it requires the stylus tip to be engaging the groove at an extreme angle, that is NOT good, either for SQ or for the stylus and your LPs. (Not every sample of every cartridge is going to readout that way, of course.)

@wlutke is all over it ! use the tools, get close, dial in by ear…and have a measurable benchmark to return to…..

Peter, a guy w something like 11 patents is a measure and listen guy also……

My my my, every single one including Peter Ledermann agrees with me on this one. Be still my beating heart.
