What is more accurate , the fozgometer or the diplay of the oscilloscoop

Benjie, When you say you were "way off" doing it by ear, what do you mean?  Do you mean that the azimuth setting that sounded best to you was way off electrically, as determined by Feickert or Foz? Or do you mean that when you adjusted by Feickert or Foz, you got a better SOUNDING result than when you tried to do it by ear alone?  After all, your subjective impression is what counts, at least in my opinion.

..just read the piece about adjusting azimuth by ear.....   Why bother...if you can get it right easily enough with a foz....loosening screws, adjusting weights, moving things....why risk bending a perfectly good stylus by mistake....why test in a wrong direction....Foz for me.

Thanks for your response, Benjie.

@stringreen -- not sure why the method for making the azimuth adjustment (ear of meter) makes any difference to how fiddly it is to do. Even with a fozgometer you're going to need to make azimuth changes and also go above and below the "correct" setting to get there. Maybe it's just a case of some arms are harder to adjust than others?

Anyway as to the question of ear vs measure I own a foz and use it to get the azimuth in the ballpark and then fine tune by ear

This stuff really matters, and the level/mirror method falls short for those cartridges (like the majority of Air Tights ime) that are not mounted that accurately. At the last Newport show 2 out of 3 AirTights (including a magnum opus) had to be mounted with a visible cant to get the azimuth right -- my PC-1 is no exception, it sounds best lilting 10-15 degrees off to the right
