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.

what is wrong is coming for a faulty design.
I think we can all agree that all arms have compromises; nothing is perfect. Having recorded and produced LPs and also having mastered them myself though, I can safely say that amongst arms its price and those costing quite a bit more,  the Triplanar offers the least compromise.

You have boasted about your arm but but it is conspicuously absent.   
You are a manufacturer not a simple audiophile/audio customer as me.
Wow. Just- wow.

So as a manufacturer, that makes me less qualified to see when someone is insulting others and making uncalled for remarks??

Sheesh.
Raul, IMO you owe Triplanar and Lew an apology. Your statements are false and uncalled for.
Btw, the OP on this thread does not posted yet he solved the trouble.
@rauliruegas , actually, yes he did. The solution I conveyed from Triplanar was in fact the correct solution and solved the problem. Please read the responses to any thread you are on more carefully before posting.


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.
Its a pretty good guess that the three arms all got the same treatment!

The Triplanar is a precision device and like any precision device, should be treated with care.

The arm uses continuous wire from the cartridge pins all the way to the connectors on the end of the tonearm cable which is integrated. This is done to minimize mechanical connections. If someone pulls on it too hard they can tighten the wire where it passes through the gimbals but as the original poster found out, its easy to fix in a couple of seconds.



^^ I think there was some confusion somewhere; as soon as I mentioned this issue to Tri, he knew the problem and the fix. IOW I am very certain that Tri didn't say that he couldn't fix it.
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. !!!
I own two of them and neither has this problem.

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.
