Mijo, The "T3F" refers to the Rabco-like tonearm that was marketed by Goldmund, originally I think with their massive Reference TT, which was then the most expensive TT/tonearm combo available, at least on this side of the Atlantic and Pacific.  I... 
Morch DP-8 arm on a Helix Two turntable
You mean the Schroeder and the Kuzma, don’t you? I actually don’t disagree with the premise there is a loose connection between the Vestigial and the Dynavector. They are both pivoted tonearms, and they both dissociate vertical from horizontal mot... 
recommended oil for well tempered spindle cup
Since the spindle and bearing of your WT TT are unlike any others, why not follow the advice from Firebaugh? The truth is that almost any good lubricant without additives will work.  
Morch DP-8 arm on a Helix Two turntable
Because this thread was brought to the fore, I see now that in March, 2021, Mijostyn likened the Dynavector tonearms to a Transcriptors Vestigial tonearm. Heaven forebid!  I have to guess that Mijo never used a Dynavector.  Very different. I am no... 
recommended oil for well tempered spindle cup
So Bill, are you saying NOT to use a single weight, low viscosity, nondetergent, synthetic motor oil, which could also be called an "engine oil"?  Sounds like you used more ordinary engine oil (likely to be multiviscosity and with additives includ... 
Why will no other turntable beat the EMT 927?
That must have been fun. You mention that the internal phono stage of the EMT927 was used.  Was it also used with the other 3-4 TTs in the shoot-out?  It is unusual that you and your friends were nearly as enthusiastic about the 950 as you were ab... 
Who Is An Expert On Acutex Cartridges?
Timel, I have always felt, and occasionally stated here, that for high compliance cartridges, in theory there is not much energy that needs to be dissipated from the cartridge body, because the cantilever and suspension dissipate most of it.  I wo... 
recommended oil for well tempered spindle cup
I am sure your direct experience is more cogent than my guesswork, but one might think that with a stretchy belt, higher viscosity would engender more belt stretching which might lead to more speed irregularity.  Just thinking out loud. Anyway, my...

There is just no need for two weights, unless you’re planning on 5000 rpm. This is not to contradict Firebaugh. He was probably exaggerating. Or picked some numbers out of the air. By all means do go with his recommendation.  
Why will no other turntable beat the EMT 927?
Pani, where and in what context were you able to audition a 950?

33 or 45 rpm is not much of a stress on any bearing using any oil. The Mobil One recommendation is good as any.

From specs alone, the ART 20 seems to be a super version of ART9, not more, not less.

What source could be better than “Mr Firebaugh”? But I use single weight, synthetic, nondetergent motor oil for all my TTs. I have never owned a WT TT.  
Who Is An Expert On Acutex Cartridges?
Timel, I actually have a Grado TLZ that I used as my one and only cartridge for several years back in the 80s. I still have its factory packaging which includes that triangular, dimpled piece of plastic for separating cartridge from headshell. I r...
