In Reply to: How long IS that arm? posted by caffeinator on May 5, 2007 at 14:51:50:
Yeah, effective length, 309 mm, per Vinylengine's database.Skip this if you saw our last discussion in a User510 thread, but here's my take on the 12 inch tonearm....
'Having tried a couple of arms now with Garrard 301's, I'll add my vote to the 12-Inch appreciation club. Somehow the twelve-inch geometry conveys even more of the un-concerned confidence that the 301's already have.
Seems to me that all pivotted arms are a bit of a compromise (compared to that nonexistent perfect lateral-tracking ideal)... but the longer 12 inch arms are simply less-so of said compromise's negatives.....
Three Inches ? Not much, really --or is it ?
Three inches more is an addition of a full third of the length of the standard nine-inch arm. Not insubstantial.A drop in tracking distortion, even at the limited levels noticeable btwn 9 and 12 inch arms, brings a further feeling of expansiveness to the proceedings... Kind of like stretching out*, feeling uncramped-up. And, as I've mentioned before, puts the armbase further in the right direction from the motor by a substantial three more inches......'
Oh, and the Ikedas and the EMTs look especially long due to their shorter headshells.... so yeah, the arm is a little longer to compensate, tallying up all the same in the end.

Don't know if the new 997 clones are longer than the originals but I thought the 997 was 297 mm effective length and was EMT's in house replacement for the Ortofon RMA297. I don't know why a different length was chosen to the standard RM series 309mm but it may be the same reason the pin layout was turned through 45 degrees. I understand that the new clones are available with either layout
Hi Andy,Not to be picky but its not a "clone." its made by the same engineer as it always was and with the same jig. Its still a EMT product.
The geometry of this arm is capable of aligning with both the G shell and A shell and can be had in either T mount or international mount pin configuration. It is a 297mm.
Reissue is probably more appropriate. Good to see them back in manufacture.
I think the different lengths of Ortofon arms are to fit the shorter (A-type) and longer (G-type) SPU headshells. Presumably the same goes for EMT, who also seem to have shorter and longer headshell (here I get a bit fuzzy though).My EMT arm has the SME (Ortofon)-style pins, not the diamond-layout EMT pins. I think you can order it either way.
