Okay. It looks like I was on the right track for azimuth. I do have a storage scope so that will help. I thought zenith could be done. IIUC, zenith is the measure of the rotation of the stylus with respect to the groove, when looking straight down from the top of the cartridge body.

I thought that if zenith were perfectly set, when looking at the Left and Right channel traces from a monophonic sine wave signal you'd see them perfectly in phase. If the zenith was off you'd see the sine wave from one channel leading or trailing the other.
I normally use either a DB Systems alignment tool or the Hoffman DIY arc alignment tool, but I've been curious to see whether I could do better using a scope.
