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.

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.


Raul, Do you have an equivalent phrase in Spanish for "You are making a mountain out of a mole hill"?  If not, try "Tempest in a teapot".  The discussion should have ended when the OP got his information.  There is hardly any audio product you can name that is completely foolproof.  In that adjective, the operative element is "fool".  We all fool around with our stuff, and once in a while improper handling can adversely play into one or another idiosyncracy of any design.

If a child spills milk on your phonolinepreamp, and it blows up, do we blame the phonolinepreamp for not being waterproof?

Tonearms in particular are oddball devices, employing many different approaches to solving the same set of problems, and, while I would not bother to take a survey, I would wager that many, if not most, have an Achilles heel.  Herb Papier, who designed the Triplanar, set for himself perhaps the most ambitious design goals of any tonearm designer of his era (no other tonearm allowed for adjustments in all planes, when the TP was introduced in the early 80s), and he met them all by taking some unorthodox approaches, from which we all benefit.  Designers that came after Herb also benefit from having the TP to work from.  (I am not arguing that the TP is THE BEST tonearm ever in the world; I am only saying that the TP was ground-breaking when it was introduced.)
There is hardly any audio product you can name that is completely foolproof.
True that.  Fools are very ingenious.

+1 to this. And note that the OP had the correct answer to his problem within just a few hours of his post - check the pick up arm wire so it is "dressed so as not to apply any force to the arm itself." This is one of the most basic, elemental aspects of pickup arm installation.

As more and more neophytes jump on the vinyl bandwagon, it's increasingly common to see that many fail to understand what's required to properly align a pickup arm and phono cartridge. Faulty installations often result, and so do faulty conclusions about equipment and what's possible to achieve with LP playback.

LP setup is not plug-and-play.
