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.

Well guys FWIW I have a Triplanar VII UII and have had zero issues with this design flaw as some are calling it. In fact once setup my arm has been flawless!!! I absolutely love this arm and like it was stated earlier with a little care and common sense this arm just works!!!
jsman, I well recall the very first time I heard a Triplanar, which must have been back in the early 90s.  That was the first time I appreciated that a tonearm could have a dramatic effect on the "sound" of a system, particularly the effect of correct azimuth adjustment.
Lewm,
I couldn't agree with you more, and that's part of what's so good about this arm. The ability to adjust it 9 ways from Sunday!!!
