I picked up my new (to me) Well Tempered Record Player yesterday. I'll write more about it later when I have more time. But I can say at this point...WOW! These folks really have something with this design.
Not only have they made a silent main bearing, the suspended/dampened tonearm produces a buttery smooth liquid sound that not only preserves innner detail, it openes it up!. For the first time, It's delivering a level of fidelity I did not know my system was capable of! And this with only preliminary set up!
As I said, I write more later. in the mean time, here are some pics.

Ok- Here's the info: and from Bill Firebaugh to my ears, not my opinion, etc..
The tone arm gets 100,000 cSt 100% silicone. The main bearing originally got "Dow Corning 200 Fluid" which I believe is 50 cSt silicone, based on looking at the Dow Corning site. Now Firebaugh uses synthetic motor oil for the main bearing and says that exact viscosity is not critical- this is for both the earlier 'tables and the current ones. He says the synthetic motor oil works at least as well and is easily obtained.
The vial of silicone shown in the link above looks a bit small and seems aimed at use for a tone arm. One vial might or might not be enough material for the cup on a WTL tone arm. With respect to using other fluids for the tone arm, Firebaugh sorted out a long time ago what works. I'd suggest using the correct fluid and adjusting damping as needed.
