Linear Tracker ...I was wondering

Terry, you are using the best cartridge for a linear tracker, very low compliance. I be very interested in what your vertical and lateral resonance points are if you have a test record that breaks them up. The HI FI News record does this. Of course your stylus wears symmetrically. The net effect of a perfectly set up linear tracker (level) is no skating. The tonearm just oscillates slightly at very low frequency. The Koetsu is so stiff you might not be able to see it. In a way you are right. Warps occur in the vertical plane so a low horizontal figure is not as significant. The best design of all might just be the Clearaudio  as the arm is short and It looks like the resonance frequencies might be closer together. I almost bought one but in viewing the videos I noticed in several cases the cantilever oscillation. The other problem is that the glass tube has to remain perfectly clean but it is open to air. 

The Trans-Fi also has a very short arm wand. I think that you are absolutely correct in your last sentence - that's exactly why I don't want one. Years ago I talked with the late Tom Fletcher of Nottingham Analogue fame, and he warned me against his linear tracker for exactly that reason, "It skips, so you clean the beam. It still skips and you clean it again. Sometimes twice is enough. Sometimes you can't see a thing and it still skips. Sometimes you clean 10 times. But when it doesn't skip, it's all worth it - to the right person."

Inclined plane. If the record groove is viewed as a curled inclined plane in which the stylus rides, then it is easy to calculate the forces acting on the stylus. An old mathematical trick: translate the problem you have into a problem you have already solved.

A plane is not curled by mathamatical definition it looks like you have founded a whole new branch of math, geometry and physics I am sure a Nobel prize is in store for you congratulations!!

@ terry9     perhaps coiled or spiral might have been a more accurate choice of words.

This is all part of a design and execution that separates the men from the boys. ....
I would not put up with that design.Like I said earlier in this thread all Linear trackers are very unique in the way they are designed and built.

Terry - very surprised you are saying negative things about another tonearm. Fremer reviewed one of the 360 degree air bearing designs, declared it better than his pivot - he could hear it- but said it wasn’t worth the extra effort. At some point we all gravitate towards convenience.

And you keep referring to the Transfi as an air bearing, but it is a multi point bearing which also includes mechanical bearing. Better to call it a hybrid.  

The most linear tonearm in both planes is a full 360 air bearing.
