TriPlanar Tips


The manual that comes with the TriPlanar Mk VII tonearm is fairly complete, but there are a few things I’ve learned only by living with the arm. Note: I do not know which if any of these would apply to previous versions of the arm. My only experience is with the Mk VII.

1. NEVER raise the cueing lever while the arm is locked in the arm rest. This pressures the damping cylinder and could cause a silicone leak. For this reason and also for safety, whenever the arm is in the arm rest the cueing lever should be DOWN. This is backwards from most arms and takes some getting used to.

2. If your Tri-Planar doesn't cue straight down there's a quick fix, which may be included on some new arms. The problem is insufficient friction between the arm tube and the hard rubber cueing support bar. Just glue a bit of thin sandpaper to the underside of the arm tube. Make it big enough and position it so it hits the cueing support bar at all points across the arm’s arc. (Note: after doing this you will need to adjust the cueing height, see Tip #3.)

3. When adjusting cueing height (instructions are in the manual) always do so with the arm in the UP position. This adjustment is VERY touchy, since the cueing support bar is so close to the pivot. Be patient and be careful of your cartridge. (Note: after doing this you may need to adjust the anti-skate initiation point, see Tip #4.)

Chris Brady of Teres told me of a way to improve cueing even more by re-shaping the cueing support. Moving the cueing support point farther from the pivot improves its mechanical advantage and makes the cueing height and speed adjustments less touchy. This mod is easier than it sounds and requires only a length of coat hanger (!), but I don’t have pix and haven’t yet done it myself.

4. 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.

5. The Tri-Planar comes with three counterweight donuts of differing masses. Many cartridges can be balanced using either of two. The arm usually tracks best with the heaviest donut that will work, mounted closer to the pivot. Of course this also reduces effective mass, which may or may not be sonically desirable depending on the cartridge. It also leaves more room for Tip #6.

6. For fine VTF adjustments don’t futz with the counterweight, there’s an easier way. Set the counterweight for the highest VTF you think you’ll need (ie, close to the pivot). Pick up some 1/4" I.D. O-rings from Home Depot. To reduce VTF a bit just slip an O-ring or two on the end stub. Thin O-rings reduce VTF by .01-.02g, thick ones by .04-.05g. Quick, cheap, effective. (For safety, always lock the arm down while adding or removing O-rings.)

7. When adjusting VTA, always bring the pointer to the setting you want by turning it counter-clockwise at least ¼ of a turn. This brings the arm UP to the spot you've selected, which takes up the slop in the threads. You can easily feel this happening.

Hope someone finds these useful. If you know any more, please bring ‘em on!

Hi all, I hope that this 'extension' of Tri's will lead to
the 'extension' of the bias-weights. Hopefuly to 3 in the near future.

Regards,
Dear Dan, My Triplanar VII came with just 1 bias weight that is to heavy for my Benz Ruby 3 so I use no antiskate
at all.
Regards,
Dear Lewm, Of course you are right.But I also used the expression 'anti-skate' and tought that I am the only one
'deprived' of 2 additional 'bias'- weights and emailed Tri to ask for clarification. BTW on his website one can see only one'skate-weight' and 3 counter-weights.However I got 4 contra-weights with my Triplanar so there is somem kind of 'justice' eventually.But even so I was always wondering
why just one (to heavy) anti-skate weight?
Regards,
Dear Lewm, We have obviously some kind of anti-skate enigma.I used to adjust this 'force' with an 'blanco' LP with the advantage that I was able to see the forces involved. Then I learned that I am an imbecile and thatthe right manner was to use the 'tracking ability test' from am test-record. I.e. if you hear the 'buzz' from (mostly) the R. chanel you need to increase the weight. I got 90mu with my (then) FR-64 + Ortofon MC 30S without eny 'buzz'. I must confess that I was very proud with this result. Then I come across an worning from Van den Hul himself: don't try to get 70mu or more,you will destroy your LP. So I give up the concept 'anti-skate' as well as the attempts.
Then Doug come along with his O rings. No way one can get these rings in Holland so I emailed Doug asking for,say,10
of those rings. No answer at all .So I must give up for the second time.
Regards,
Dear Lewm,We are coplaining about those AS weights,it seems to me,to the wrong address: to each other.
I caused the misunderstanding by using the exression 'bias-weight'. This was caused to me 'cause I thought that this saying was a joke: 'The USA and the UK are different countrys divided by the same language'. I am an regular visitor of the English eBay.co.uk. And there overyone is refering to the 'BIAS-WEIGHT' and nobody to the 'anti-skate'. So I was once more caused,by some of our members,to
think that I was the only one with just one of those 'anti-skate' weights. So I emailed Tri with a very naive presupposition that I will get an answer. I asked about those (imaginary) 2 extra anti-skate weights. However I am
sure that he is the 'right address' for our complains.The only problem is how to 'get' to him. Well I may 'get there'
by accident so to speak. I got an email from an very kind guy, Paul,who seems to be Tri's friend .So I made my proposal to Tri via Paul. The proposal: we need at least one extra weight that is the same weight as those Doug's 5
or 6 O rings. So we will see.
Regards,
Dear Lewm,You 'dwell (about the things)just before sleep' and are 'much smarter then'(08.17.09).
The total opposite was the case with me.I was wrestling with just one thougth and was not able to sleep at all. I am reluctant to say this but the Triplanar VII cost 5000 Euro in Europe and I thought that my 'specimen' was incomplete but also that I had some kind of 'human right' to all the 'bias-weights' that others had. One thought can
hardly qualify as 'reasoning' but probable well as 'obsession'.
I am ok now and even the O rings are on the way but I still
think that such an expensive tonarm should have more of those weights. Bisides why should I mess with 'Rings'(I hate Wagner,btw) 'on' this kind of tonearm?
Regards,
Dear Lewm/Atmasphere, I am even more puzzled with this anti-skate enigma as before.It looks as we are talking Unified Field Theory and I thought it is about friction.
I perceive some kind of attitude, by some members,to protect Tri from 'onjust arguments'. To my mind Tri is better 'served' by critical feedback from his customers.
According to Atmasphere he is aware of the problem. But the fact is:he is still producing this to heavy AS.
And then the dramatic exaggeration:'if manufactures had to account for all the crazy things we do...' + searching for
our own 'competent machinist'. My God. All I, and I assume other,want is an smaller AS.
To my mind it is CRAZY to pay 5000 Euro for an tonearm and
then search for an 'competent machinist'. I will then rather search for an other tonearm.
Regards,
Dan_ed, My 'agenda is beginnig to show'. My God I had no idea that I have one. What can this agenda be? I am from the former East block so I am probably an KGB member. End then I mentioned the 5000 Euro price twice in what I thought to be the right context, so you are entitled to call this 'keep repeating the price' because it was more then once.Then it is very interesting for us in Europa that the Triplanar is $4K in the USA. Alas you forget to mention: 12%import duty,19% VAT,30% importer fees and 30% dealer-fees.
What I forget to mention in my former contribution was that
even Tri himself don't use the AS weight he produce.
But then I am 100% sure that my my FR-64 had two bias-weights because I was able to get this 90mu that I mentioned with the small one.So even in the 80 one could get more AS weights. As Dertornarm stated before those are
mechanical matters and mechanics don't care about our subjective preference. But according to you and some others it is nearly impossible to get AS right. But whay bother then?
Regards,
Dan_ed, I made the proposal for ,say,two added weights for our Triplanar(08.14.09). I then used the expression 'bias-weight' and caused some confusion,etc.
Now a proposal is not a kind of statement or sentence that
can be true or false. So the logic is not about those kind
of sentences. My proposal is not accepted for different reasons.Many prefer the O rings and those are also weights
though 'tiny' kind.
I made no single statement about,say,'the quality' of the
Triplanar but only expressed my 'wish','desire',etc for
more AS weights.
Now you constructed somehow my proposal or wish as a kind of premise and 'deduced' from there some bewildering statements:
Nandric has his own 'agenda' + the agenda 'projected from Dertonarm'.
Nandric 'don't like the Triplanar and prefer another arm'.
Nandric use (the forum) as 'a platform to tell us what (he)
don't like about the Triplanar',etc. Bravo!
BTW your guess about the Phantom is as successful as your
'logical deductions';I never owned an Phantom of eny kind
and I am also not in possesion of any FR's of Dertonarms kind.Besides I am also an 'owner of Triplanar' so it is very difficult to put me outside the quantifier 'WE'(the owners).

Hi all,This tread is not progressing and it may be my fault.There is always this problem how detailed an contribution should be with the obvious chance of incompletness. So I mentioned that 'proposals' are not statements that can be true or false but deed not,say, elaborate on this. Well of course one can argue about the sense,the nonsense,the practability.etc. of an proposal.
In my proposal about,say, more AS weights the argument was:
there is no way one can produce one or more AS weight such that this will solve the problem. I.e. assuming some metal-kind of AS weights. Regarding the O rings,that are also
'weights' the argument is,I assume,that those are such 'tiny' weights that one can add or reduce the weight in such small increments that one have more chance to rich,say, the Nirvana.
Well I like to try both. The O rings are on the way and I also discovered one ,I hope,'competent machinist' as Lewm
recommended.I ordered 3 AS weights so I will,I hope,reach some kind of 'super symmetry'.Besides I will have my own cardinal number 4 because there will be as meny 'F things'as 'G things' in my 'set' of weights so I will be able to establish 'one to one correspondence'whenever I will.
I also owned the model VI of theTriplanar and had the same problem with the AS weight. But I thought that I can solve this problem by myself and bought the most complex 'FERM
TOOL' ,with 40 attachments. The idea was to cut progressively 'tiny' parts of the AS weight and then check the results,etc. Alas I cut also some pieceas of my left-hand finger. So I know that this Lewm is a smart gay,even long before he is going to sleep so no wonder he insist on a 'competent machinist'. I hope that I also become smarter in between.
Regards,
Dear Lewm,The problem is,as always I think,in the premises
or assumptions (aka'knowledege versus ignorance'). Papier
was a genius so he of course thought about his anti-skate
construction and the AS weight. Then there were different
methods to adjust the ant-skate. I already mentioned: grooveless LP; the test-records with 'tracking test',etc.
Those are in some sense 'prescribed' or 'recomended' to us.
So we used these methods assuming that they are 'right'.
But then we learn that this is not the case so we become insecure. Not a pleasant state of mind. So we want to try
something else or anything. Our forum is mainly about such
'dilemmas'.So we get different 'proposals' that I also mentioned and even tryd to 'disclose' their 'nature'.But our forum is also about,say,'passion' so some members get
angry when they hear something they don't like. This causes
then 'accusations',etc. I owned the Triplanar VI and own
the VII and am 'in'the Triplanar for more then 10 years.
But I am still 'pressuposed' by some members to 'hate' or 'dislike' the arm. You are asking why I am 'convinced'
that this (actual) AS weight is to heavy. Well Lewm this
is my assumption because I learned that others don't use this weight at all. But I also mentioned that I give up
the 'concept' anti-skate as well as attempts. Not 'exactly'
true but this is,it seems to me,a kind of evidence that I have no idea what is 'right' and what is 'wrong' with this
anti-skate enigma.But I also want to try 'anything' so I will get the O rings as well as 3 more AS weights. My,say,
'provisional' method is to use the test-record and 'rich'
50 mu (to be sure)because I learned that this is 'necessary' and then do the rest by listening to the so
called 'critical LP's' ( Rigoletto but not the 'Ring').
Regards,
Dan_ed, No harm done but I need,I think, to apology to Lewm
for the 'smart gay'. I have also seen this but to late. In any case I am to old for Freudian 'slips'. BTW I live in the Netherlands and here it is no problem at all wich kind
one is. I am originaly from the Balkans so I needed some time to 'get' the 'Dutch way' of thinking. But I have more
problems with your,say,'Europe attitude'. May I remind you that Einstein,Godel,Tarski,Carnap,e.a. come from Europe to
the USA and all of them were not 'perfect' in your language. But all of them were university teachers in your
country. So am/was I in Holland.
But this thread is about the anti-skate and I forget to mention the Sony 1500 (?) tonearm. It was in the 80 that
I have seen this arm. I was then 'in' the ADC carts,still own the 25 with 3 styli (sic!)so this arm was to heavy for
the purpose. But I still remember this remarcable anti-skate 'provision' that was variable,depending on the record
radius. Never seen such an construction since.So I assume that the most tonearms have,say, an constant 'AS force',irrespective of the record-radius. So this is an problem because this force is not equal on all of those radiuses. So I think that our search for 'near perfection'
will result in some kind of 'second best' solution. Anyhow
we are trying our best.
Regards,
Dear Dan, This have nothing to do with anti-skate but I think that it is very important not to distinguish between
American and Europian intellectual tradition;they are the same and stem from the Greek tradition,say, Plato and
Aristoteles. I admire your brilliant logician Quine as well
as linquist Chomsky but I never think of them as Americans.
I think of them as 'part' of an great universal tradition that is called the 'search for knowledge' and in this search everyone is welcome irrespective of his country.

Dear Lewm, Twain is as popular in Europa and I knew about
this 'Rumor-incident' but missed the connection. Anyway
the 'rumors' about the first part of my unfortunate word combination are not 'exaggerated'.BTW my favourite is his
story about the 'unbelievable learnig capacity' of his father.
But I hope you will be as Stoic regarding this information.
Your assumption about the number of counter weights is wrong. I was glad with my cardinal number 4,as many F's as
G's (aka Hume's Priciple) or as many counnter weights as AS
weights but by my recounting I discovered that I own 5 counter-weights. I overlook the small one on the back side
of the 'end' tube . Obviously meant for the very small weights increments so the owner can adjust his TF to,say,
1,998 gr. But I also thought that this 'invention' was a
kind of 'intellectual property' of somebody else;one of our
member I belive. Not without selfinterest because I am supposed to know something about the subject (I teach this subject).
So Lewm the discrepancy between those weights get biger and biger and your position (defending the actual one)
waeker and weaker. Or so I thought.

Dear Dan_ed, We are some kind of international community with the same hobby. The only thing that matters is the
content of the information the members have to offer. I am reluctant to refer to Raul but we all have some profit from
his contribution. There are the so called language-purist,
mostly the language teachers,but this is,at present time,
pathetic. I am more familiar with language philosophy (logical as well as lingustic) then with analog gear. So I
think I can disentangle this language myth. I am communicating in 5 different languages daily 3 of wich I am
fluent in. No problem with the other 2 that includes English. So this language myth is easily 'refuted' if you think of all of those scientist that come from Europa to the USA and become university teachers that further the
American leadership in science. If you think that they all
ware fluent in English then you have no idea what you are talking about. I have no problem at all with your qualification that I come across as a 'non-intellectual American'. But this qualification may say more about you then about me.

Dear Paperw8, I am not sure what you mean by 'logical explanation' (08.27.10). I thought that logic is about 'deduction'. Ie if the premise is true and deductions
correct, then the deduced statements must be also true.
Are you questioning the premises of your,uh, opponents?

My problem may be connected with Syntax ''discovery''. But first

thing first. My armboard is made by Kuzma for my Kuzma Stabi

Reference. The distance spindle -pivot is exactly 233,5 mm. I also

own Mint tractor made specific for my Kuzma /Triplanar combo.

My problem is this. I use the so called ''tracking ability'' test records

as a kind of orientation for the needed VTF. My goal is to get 60

microns ''pure'' for any MC cart I use. Don't ask me why (grin).

Well my problem is that my Triplanar ''refuses'' to track better

than 50 microns with whatever cart.  Even the carts which track

70 microns with my FR-64 S.
