Ha! Looks like I have to eat my words... sorry about that.
TriPlanar tonearm outward skating issue
Hi all,
I have been trying to research a solution to a recent issue with my TriPlanar VII UII tonearm that I bought a couple years back.
The tonearm seems to want to skate outwards, even with zero anti skate applied and the weight removed from the little anti skate arm. It is evident at various settings of VTF, VTA, etc. The platter is very level and everything seems to be aligned OK. This outward skating force is very light in the outer grooves and becomes stronger as the cartridge gets closer to the end of a side. In fact, as it traces the lead-out grooves at the end of a side, the tonearm sometimes thrusts outwards across those grooves back into the last track. Very scary!
A visual check of the cantilever azimuth seems to confirm an outward pressure from the tonearm since the cantilever is leaning with the stylus end closer to the spindle.
I can’t seem to find any information online about this phenomenon.
Any insights and recommendations would appreciated.

Staying out of this mud-wrestling match, but I want to point you to an annotated photo I made to work someone through a wire dressing problem with his Tri-Planar. The owner had purchased his tonearm used and the previous owner had obviously mishandled the tonearm. Here’s the photo: http://galibierdesign.com/images/galibier_forum/triplanar_wire_routing_annotated.jpg Ralph is absolutely correct (quoted comment, below), and the above photo shows what a correctly dressed cable should look like. I would contact Triplanar; but I’ve talked to Triplanar about this and he says that this problem can occur if the interconnect cable is pulled too hard. It causes the cable to not have enough slack going through the gimbals. ... Thom @ Galibier Design |
Nice photo Thom! A picture is worth a thousand words. Salectric - thanks, that’s certainly been my experience in supporting customers remotely. It has most definitely upped my photo editing game ;-) The time is overdue for me to up my video editing game as well. Which is what I wrote also, in my post that followed on to Ralph’s first post. I’ve had it happen to me, and the fix was very simple once I was able to discern that the wires were hanging up the pivot. I’m in good company. Lewm - I confess to only scanning this thread before posting - especially after watching the conversation go a bit "off the rails" ;-) ... Thom @ Galibier Design |
