"Straight" talk

@don_c55, you are assuming that the stylus is perfectly aligned and affixed to the cantilever with absolute accuracy, which rarely happens with a hand made component.

Slaw et al.....without looking at the speedometer...can anyone tell when you're going 56 mph....

@stringreen .... how do you tell your Foz , is actually "correct"? I'm guessing like those you shade, your final acceptance is with your ears. If it was off , your stance is no, its correct even if your ears tell you different ? Likely not , so that said if you know what correct is then how can you be so flippant that it can't be done by ear from the get go. Sorry I find the logic flawed to assume a meter is the metric of choice that your ears make the final decision on.
Your speedometer analogy,.....can you tell your foz is correct without hearing results after its set...........

+1 do it by ear. Especially if you have a dual pivot on your vpi arm wand - makes it easy peasy and you don't mess up your vtf every time you adjust it. And also if like me your fozgo stopped working and you don't want to Spring for another one
