Tri-Planar Vll "SE Upgrade"

Dear @bdp24 : EPA 100 models by Technics uses 20 of those rubies in its bearing. Terrific tonearms, very high quality performance levels.

SME uses ABEC 9 bearings. Brickman are very good too. I think that today there are no true bad tonearm designs.

As the GST 801 the EPA ones are four point bearing. There is lmost nothing new with pivot tonerms designs but the Thales Statement design that is  true evolution in pivot tonearm designs.

Dear friends: Not only here but through other threads ( different or similar subjects. ) were  exposed/spreaded/posted  several lies that per sé is totally dishonest. Lies in favor of what? because here are facts that proved those lies and inexperiences  as in other threads too.

@tri-planar is not the guilty about but only a " victim ". In the site there is no spec for bering tonearm horizontal/vertical friction and its measurements about.

Btw, the AT tonearms came from the 70's and HP started in the early 80's. Whom copy whom on that: " same plane " bearing/Lp surface ".?

In reality that copy word exist only on those tonearms I mentioned were a true copies.

i spent 30 years at Boeing...some of them putting bearings in orbit.....and well other interesting things.......
always fun to learn...
