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.

Its also easy to fix- just extract some of the wires from the cable where the clamp is mounted at the base of the arm so as to give the wires a bit more slack.

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.
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.

Lewm - I confess to only scanning this thread before posting - especially after watching the conversation go a bit "off the rails" ;-)

Dear @atmasphere : I'm talking as an audiophile for audiophiles and I'm totally unbiased in favor or against Triplanar in this specific issue. For whatever reasons that I do not care your posts here and in the other thread seems to me ( I can be wrong. )  are biased.

Anyway, all the gentlemans that posted here and that I know very well are experienced audiophiles not roockies. Two of them with that trouble: lewm and wrm57.

Now, Triplanar is not the first and only tonearm that's wired all the way down to the input phono stage connectors. Problem is that in other tonearms that troubles did not happens like what we are attesting here.

As an audiophile and with all my respect to you and Tom ( hi !. ) for me the tonearm has an inherent design falult/problem and in the future must be fix it.
This kind of behavior with experienced audiophiles can't happens. This is my take about.

If Triplanar try or not to fix it by design is up to them and as I already said: I don't care about, I'm not an owner of this very good tonearm.

Of the hundreds or thousands ( I don't know ) of Triplanar owners I don't know how many of those owners have the same problem that they not detected yet. Can't detect it because the intensity of the trouble is not exactly the same in each tonearm where is happening. That's why I invited to Triplanar owners ( or other tonearm owners. ) to try the AS test I posted7explained in this thread.

As an audiophile I don't like to diminish in any way this kind of critical subject in any tonearm. Well, that's me.

Regards and enjoy the MUSIC NOT DISTORTIONS,
R.
