I see... luckily when I put mine together the head shell stayed put, I mounted the cartridge, and did more arm adjustments to get it parallel, and then the ball just so in the goo. What some of you have had to do, either from fiddling errors, or because you just plain want to fiddle, is go back to the old ways of x's and lines and paper. I let Mr F do that!
if he says it's good then it's good.
But, he can compute and theorize all he wants, and he has!, I just want to sit and listen. And boy does it sure sound great.
Good luck out there! I'll try and get a photo of mine up soon...
