For the life of me, I can't get this darned thing aligned. I have a 3009 Series 2 Improved (non-detachable headshell) tonearm on a Thornes TD-125 with an original Thornes cut SME armboard. I have an early 3000 Series 2 Improved (serial# 129xxx) and I'm using the early SME protractor from VinylEngine. With the arm slid all the way toward the platter, the alignment is quite a ways off. Any suggestions on how to get this thing aligned? The needle is sitting in the hole on the protractor.
