Grimace,
looking at your turntable, I don't think the 12 inch version is going to fit. You need at least 311 mm for tonearm pivot to to spindle. Whereas the 9 inch version fit fine with pivot to spindle of 214mm. I would double check with SOTA.
BTW, the AT OC9 sounds wonderful with the Ortofon arm. I own the OC9 (Lryalike) and it is a very detailed cartidge with a nice tight bass, at the price it is very good. Coupled with the ortofon arm just relaxes the cartridge a little to show it at its best.
