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.

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.
+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.

Triplanat has a history and the other thread has more " data " and there are other " data " for years. Problem is that is unknow information for you, you just has no Triplanar experiences.

Again Raul, you speculate, and then pronounce your conclusion. And once again, your data is wrong - actually, you have no data in this instance and are just guessing.  Your conclusion is wrong, too.

Because you have such a passion for audio, I urge you to study logic and statistics. It will help you make better choices and offer more meaningful advice to others.

The answer is yes to all your questions in your first sentences.
Sorry, but I don’t believe that the posters here shipped their pickup arms to you for evaluation. You’re just speculating.

in this thread 3 of 3 audiophiles that own the tonearm shared the same trouble.
I don’t care what you think but if 3 of 3 has the same problem something is " wrong " with that tonearm ...
Sorry, but that’s the logical fallacy often called the "Texas Sharpshooters fallacy." It’s related to the "multiple comparisons" problem that can happen when statistics are misinterpreted. You are considering only a small subset of data. Worse, you've appointed yourself as judge, jury and executioner regarding the status of these three pickup arms - about which you you know nothing first-hand, but instead rely on information that doesn't even rise to the level of hearsay.

After several manufacturer revisions/up-dates ( many over many years. ) today still looks as still an unfinished tonearm design.
Hey Raul, have you examined any of these arms that you claim have a defect? Have you ever actually even seen a Triplanar arm in person? Have you ever heard a Triplanar arm?

The OP says his problem's resolved, and yet you call the Triplanar an "unfinished" design?

Sorry, but your determination is based on information that doesn't even rise to the level of hearsay, Raul. It's just speculation, and ill-considered speculation at that.

What is something " weird " is the very high tolerance levels that some times we audiophiles have with manufacturers or retailers when they just can’t fix a problem like the @wrm57 with his tonearm ...  where is that tonearm manufacturer that did not fix aproblem in its manugactured tonearm? , I think that when we take te responsability to fix a manufacturer problem we are taking out the main responsability of any manufacturer/designer ...   if Triplanar comes here and says that that issue is part of the toneaerm design at least the owners needs to know it but no explanation and not fixed trouble. !!!
That's absurd. The manufacturer has no obligation to come here and tell us about this pickup arm. We don't know if the OP even bothered to contact Triplanar. We don't know whether it has a manufacturing defect or not. Perhaps the OP purchased this used; perhaps it's been misused or abused in some way, or damaged in shipment, or improperly installed. The problem as described here should in no way reflect negatively on Triplanar - we have no reason to believe the manufacturer is at fault in any way.

That problem is a real problem with your tonearms even that one of you " solved ". That's not a normal behavior.
I'm with Raul on this one. The OP treated the symptom of the pickup arm problem, not the root cause.

@cleeds: Good thought but the Triplanar has a captive cable fixed to the base, relieving stress on the arm from the cable.
Given the skating issue you described, this captive cable warrants close examination.
Have you checked the wiring of your pickup arm? It needs to be dressed so as not to apply any force to the arm itself.

The Triplanar arm allows for azimuth adjustment. Have you adjusted it for proper azimuth?
