Leak did one with an adjustable sprung loaded ball supporting the tube near the bearing.
When we were doing the arm for AI we played around supporting various arms having removed the counterweights. Of course the system of support has to be able to move in the horizontal plane along with the armtube as it traversed the record but that wasn’t difficult to arrange & I often ended up using a rubber band to hold the tube up enough to allow for the correct amount of tracking force when the stylus was in the groove… It did really good things with the bass, the like of which I don’t think I’ve heard from any conventional arm. Lots of other issues to be overcome but that aspect was exceptional.
Unless Pete wants it back soon (@coco let me know if you do!) I’m going to try the AI arm on my SP-10 as soon as I get the system up and running. I’ll need an arm board, but I reckon I’ll be able to make one in an hour or so from a nice piece of teak I have.
Rabski will have built his 300B amp before Pete gets a TT running again.

*Hold on, that’s utterly ridiculous. What was I thinking? The Rabski/amp deliberation is known unit of geological time like the Pleistocene or Cretaceous periods.
Bought a pair from a Birmingham based valve seller for £20. Used them for 10 years. Broke one & sold the other to someone in Tokyo for £700. Too cheap judging by what they fetch now.
It’s a motor unit as pictured, no plinth. Technics will be making their own plinth available. Doubtless there will be some bespoke after market plinth offerings too.
