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 @lewm : Rigth now I'm not sure if you or other audiophiles will see photos or design explanation through the internet because I'm thinking to do it very personal with each single gentleman that can be interested with. 
The tonearm already has a name: PCTI Limited Edition.

A kind of desiogn and targets as my tonearm is almost an " endless " audio item. Through the years I think that always existed something else to fulfill the targets.

Btw, it's a unique universal tonearm design  but not perfect ( nothing is in audio. ) and with its own trade-offs that have to be chhosed because the targets and " sacrifice " nothing against its quality performance ( neutral item. ) to mate with any cartridge at its best.

Dear @atmasphere here  /friends: @cardani / Carlos is a symphonic Orchestra player in Xalapa ( way different place that México city where I live. ). He is a young gentleman with a huge musical talent, I was lucky to know him years ago because our mutual love for the MUSIC.

At random Carlos had to comes to México city 10 days after both terrible earthwakes here and was when I meet him at my place.

He is the only gentleman that not only see my unique tonearm design but the only person to listen my room/system with.
Normally my audio friends come to my place not only to enjoy MUSIC but to talk on what we like and meet other common friends but since I have my prototypes under testing and deep evaluations no one came here.

He had this privilege and I know was a privilege to listen it because I know that for him was an unexpected audio experience.

As you know this tonearm " adventure " started around 9 years ago and gone so slowly because I'm not in the audio comercial market ( I'm an audiophile. ) but the more important issue was that the design targets were and are a true challenge and very demanding due that not only had to fulfill the cartridge needs in deep but that I must be satisfied with.
Btw, these are the words in a Mexican song: " the important issue is not to arrive faster but to know how to arrive ", something like that. At the end this is not my way of living$$$.

As Carlos said my tonearm design is a unique a truly unique one, it's not " more of the same ". My target was similar that when we designed and manufactured the Essential 3160 PhonoLinePreamp " no more of the same ", even today has no competition at any price. 

Our tonearm design competes with no other tonearm in the market, is just unique and the best is that any cartridge always shines and shows it at its best when mated with: a true universal tonearm design. This is not marketing slogan, I made " thousands " of tests with almost all vintage and today top LOMC cartridges looking for that " shines " and the tonearm performance level always " made " it. 

Due to its manufacture complexity I'm evaluating the financial needs to build perhaps no more than 25 units additional to the ones I will own. If we put on for sale this will be not through the net and will be direct sales. I'm not totally sure yet how to handled it.

Anyway, the tonearm exist.

Dear @thom_mackris : Here and in several threads I participated I posted that exist no-perfect audio item and that what makes a differences for the better are the good or not so good manufacturer/designer choosed trade-offs. For me that trade-off

I posted and ask that any TP owner or even owner of any pivoted tonearm make a test with VTF at zero and AS at " zero " ( tonearm in horizontal/vertical equilibrium. ) putting on at different horizontal positions looking if the tonearm mantain a dead-steady position where we posicionated, this have to be at all the LP surface length.

Seems to me that no one of you did it or decided not  share with us. So
I have to be direct: @lewm did you tested your TP in the last week? what found out? and Tom what found out on that test with you TP tonearm? or any one else.

Thank's in advance.

Regards and enjoy the MUSIC NOT DISTORTIONS,
R.

Btw, good that we have and discuss our differences  because through those discussions every one learns or confirm " something ".

 
@atmasphere : I'm not insulting " others " as you said. I'm only telling that something is wrong down there and what is wrong is coming for a faulty design.

So maybe according to you if I give my opinion of  something anormal in an audio item behavior then I'm insulting the manufacturer. That's you not me.

Enough.
R.

@lewm : I'm not attaking the Triplanar in any way and what for you is a "   very minor idiosyncrasy of the TP " for me is a fault in its design.

What for you is "  a problem that is easily avoided if one takes the slightest care " for me is a fault in its design and must be not present for whatever reasons with any single customer.

Btw, did you already the test I explained here with your TP? is it steady at any horizontal position you choose?

About my Esential I posted in this and other forums talking on it and vs other similar products. Here we are not talking of tubes and he is making a " hard deffense " of the TP because is biased to where I'm not and even in the past when I talks about the Essential I always gave the facts and testimonies about that fenomenal unit where you can't ever dream on that kind of quality level performance and when I compared against other units as: Boulder, Levinson, Krell, Halcro or darTZeel ( tubes has nothing to say by comparison. No contest at all in anyway, same for hybrids designs. ) I posted in the forums the diagrams by ST vs my Essential same measures. Btw, my unit had not the very high prices of Boulder ( around 50K+ ) or any other top units. Today is still a challange for any today similar product. So what?.

In those times people like you " attack " me because I was making those true comparisons vs competiors and that this was not " usual " but what for some people is not " usual " for me not to say it is deshonestity or be hipocrit.

As I have nothing vs TP I have nothing against atmasphere . That's not the issue. The issue is that you as other audiophiles more and more are less demanding that my self and this is the differences between you an me: huge differences because of that. 

Btw, my tonearm design is alive an running at my place but this fact has nothing to do on what I posted here about the TP where in 3 different posts I said: is a very good or good tonearm. Again, this is not the main subject I?m talking about.  Got it?

Dear @thom_mackris : I know that you really give a very good support to your customers, good for that.

The issue of my coments is way different from your " feelings " about. Looking again the first picture you shared here now I understand why is a design fault in the Triplanar that’s easy to fix and not only that but give a better quality performance to this good tonearm. Of course that it’s up to the manufacturer stays as is or make some changes.

@atmasphere I owe nothing, problem with you is that I’m not biased to like you. You are a manufacturer not a simple audiophile/audio customer as me. Btw, your opinion of " flase statements " is false because your unknowledge level/ignorance in that special subject. Period.

Dear @lewm : Due to your last post I'm a little disappointed on what I was thinking of you as an experienced audiophile. Never mind.

I own some bulletproof/foolproof audio items. Of course not that stupid milk's child example you posted.

Almost all audio items comes with an intrinsecal trade-offs design. Those trade-offs are the ones that makes the real/true differences in between similar audio items.

Now and depending of whci audio item we are talking about some kind of trade-offs are just unacceptable like this one in the Triplanar. We are not talking here of the VPI unipivot  we are talking of a good tonearm in a price range that certainly is far away to be an entry level one but we are talking here of the more critical an important cartridge's " slave " that it's main target is to fulfill the cartridge/LP needs.
Things like this subject in the Triplanar and the support many of you do is the main obstacule for analog can really grow-up.
Is " sad " to see audiophiles that over the time are less and less demanding on quality performance audio items. That attitude makes that less and less the manufacturers have real/true chalenges to fulfill the audiophiles targets.

INCREDIBLE for say the least. ! !

For you post you are satisfied with, fine with me and I don't care about. As I said I don't care about Triplanar, I'm not an owner and certainly I will not be a owner in the future.

Every one enjoy what we have. Good for you and other Triplanar owners.

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.

@cleeds : Certainly not the this thread users.

3 of 3 is a fallacy, ok with me. That tonearm design has to be fix it about, fallacy or not. At the end as I said it I don't care about Triplanar.

Small subset of data?, 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. At least is what you showed here through your posts.

Anyway, enough. Who cares about.

R.
Dear @cleeds The answer is yes to all your questions in your first sentences. 
My first experience with the Triplanar in a  top quality performance  system was in Dougdeacon ( the OP in the other triplanar thread. ) place in USA and after that around 7-8 times.

Btw, the OP on this thread does not posted yet he solved the trouble.

Now, 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 that has to be fix it by the manufacturer for can't repeated again with his customers.

You are " looking " how to hit me ( as always. ) with out success ( as always.

Dear @cleeds : J.Carr Lyra designer just two days ago posted about his products ( different issue. ), in the VPI thread after big pressure by customers VPI posted, PL of Sounsmith posted, Atmasphere posted in specific of his product design ( different issues each one of the manufacturers. ), Anvil TT designer posted a few days ago and audio distributors that care of their customers comes/came here and post. 
You can see very clear that it's not " absurd " as you think.

But different " problems with the Triplanar tonearm is a historic " behavior ". In 2005 in a thread customers disclosed 9-10 " pproblems that they solved by it self, by coincidence one of those troubles was the AS issue:

""  Changing the cueing height affects the point where anti-skate kicks in. (Yes, it's weird.) Once cueing height is satisfactory, adjust the short pin that sticks out of the front of the cueing frame. That pin controls where the anti-skate dogleg first engages the knot on the string.  """


After several manufacturer revisions/up-dates ( many over many years. ) today still looks as still  an unfinished tonearm design.

Dear @wrm57 : It was not you who posted:

""" Tri sent me a lighter counterweight but it’s still too heavy. So I fabricated a lighter one still, comprised of two layers of blutak between three small titanium washers. Slides on, stays put, and allows for adequate fine-tuning of bias. """

that post tell us that was you not Triplanar whom fixed the problem because the advise Triplanar gave you not works. Was you too who posted:

""" Yes, the wiring was my first thought, too. I’ve played around with the cable to no effect. """

But lewm had the same probelm that he fixed too in a simple way.

@cleeds , for whatever reasons we have just here 3 tonearms with same trouble. I don’t care about Triplanar tonearm per sé because I’m not an owner of it, I just read 3 problems here with a 4K+ tonearm design.

Question: what’s wrong down there?. Is it a problem developed by the customers or something about the design of that tonearm?

If what Triplanar said to atmasphere is the problem seems to me like a design problem that could be fix it to not repeat again in future Triplanar arms.

R.


Dear @cleeds : Maybe you are rigth ( for me is not absurd. ) but other than the OP wrm57 had the same problem and after he contacted the manufacturer the advise he gave him was not works and was wrm57 whom did it and posted here what he did it.

In my first post I told the OP to put in touch with the manufacturer, is up to him do it or not instead to following asking about.


It could be interesting that the Triplanar owners can make a simple test: with the AS mechanism at rest put in horizontal equilibrium ( zero VTF. ) the tonearm and see what happen and if no other tonearm shows what the OP and wrm57 posted then there is no problem in the design. In that test the tonearm must be totally inert at any point/position we moved in the horizontal plane.

Well, we can make this test with any tonearm we own and see what happens.

In the other side for me is not absurd that a manufacturer could comes here to help a customer. Never mind, I explain my point.

Dear @cleeds : 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.

I see he is satisfied when was him whom fix it.
My question: 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 and that’s why I said seems to me " weird " the wrm57 attitude but this attitude it’s not the first time we took it, any one can read the VPI thread here where manufacturer just does not takes its main and only responsability after the product be sold.

Now, 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.  !!!

Dear @shayes002 @wrm57 : That problem is a real problem with your tonearms even that one of you " solved ". That's not a normal behavior.

Due to past experiences I had could be that the problem is in anti-skate mechanism where the thread in that mechanism does not " flows " in easy way ( to much friction. ) or that the thread is to short/length to achieve zero bias when in rest position.

Those 2 kind of problems I had in the past with tonearms and I can't be sure that is what's happening in the Triplanar. What I'm sure is that is unacceptable in any tonearm design. It's obvious that something is wrong and the best way to fix it is that both of you put in contact/touch with the today manufacturer.

Yes, I read that @wrm57 did it in the past and the manufacturer just did not fixed but it's him who has the responsability to do it.

Maybe there are other owners that has a " lighter " problem with out know it.

Normally that bias mechanism is " calculated " to start to works from the begin of the LP at outerward groove and goes higher in small force increments as the tonearm play at the inside grooves.
