SUPATRAC Blackbird Sideways Uni-Pivot Arm is being called a "game-changer"

[sonddek]

Ladies and gents, it has been many years since I've posted on this forum, so I hope this is the right place for this message.

The short story is that I designed a new kind of tone-arm bearing during lockdown because I had too many turntables and not enough good arms or money.

The basic principles of the arm are that it is a type of ultra-rigid uni-pivot which unlike traditional uni-pivots is not free to roll/wobble laterally, and it is effectively immune to scrubbing at the bearing point.

I now have a patent in process and am selling the arm to the bold under the name SUPATRAC Blackbird.

Customers have already installed it on decks made by Technics, SME, Brinkmann, VPI, Linn, Well Tempered, Lenco, Pro-ject, Ariston etc.

Please feel free to ask any questions you may have.
