mikelakers, I’ve actually been emailing with Lee at Acoustand for the past several days as we try to determine whether his plinth will handle a Triplanar. He has never made an armboard for this arm.
Mounting a Triplanar or similar on an SP10
Has anyone tried to mount a Triplanar on an SP10? I was trying to do it tonight. Because of the fact that the Triplanar mounting flange is offset considerably to the left of the pivot point of the tonearm per se, the only way to mount the arm in proper position for correct pivot to spindle distance (233.5mm) is to have the arm overhang the table by a considerably amount when at rest, at a severe angle. It appears that if one wants to use a 9-inch tonearm on an SP10, it had best be one in which the vertical shaft and the pivot are in the same vertical plane, like 99% of the Japanese tonearms of yore. If you are an esthete, like me, you will dislike the assymetry, but I may decide to live with it. I also now understand why a lot of guys use 12-inch tonearms with the SP10.

Well, I’ve possibly answered my own question. Here’s an example of a successful mounting, near the bottom of the page: https://www.vinylengine.com/turntable_forum/viewtopic.php?f=16&t=60342 So, it apparently can be done, though whether on an Acoustand plinth remains to be seen. Bill |
To answer the question directed at me, no, I never mounted my triplanar on my SP 10 Mark III, even though my plinth is custom built out of slate. What I did do was to purchase a Reed 2A tonearm that is 10.5 inches in effective length. The added length solves the problem I described in my original post. If I were doing the same thing now, I would consider the purchase of a 12 inch Triplanar. (This thread is 9 years old.) Keep in mind that this issue only pertains to tonearms where the VTA adjuster is on the spindle side of the pivot point. There really is no problem with conventional 9 to 10 inch tonearms. |
