Tube question - who makes Magnum Dynalab Reference 6922 Cryovalves??
"The tubes (both old/new production) were later cryo'd by outsourced providers." That's exactly what I said too, or was trying to say.

Agree, centripetal force, in the Newtonian sense, is not the issue.  I am aware that the "real Wally" passed away a few years ago. I just figured "wally" was a reasonable way of indicating that I was responding to your post.  
Tube question - who makes Magnum Dynalab Reference 6922 Cryovalves??
I strongly doubt that any real tube manufacturer ever cryo-treated their product.  In my experience, that is always an option occasionally offered by the better tube vendors.  But I am always willing to learn something new.  
Classic Ortofon Cartridges: The MC2000 MK II or the MC3000 MK II?
No argument here.

6922s are very plentiful, similar to 6DJ8 and 7308. If you want reliable sources, I’d suggest RAM Labs, Jim McShane, Antique Electronic Supply, Kevin (can’t recall last name). I have left out other reliable sellers, but don’t buy off eBay unless y... 
Luxman PD 441 lubrication
Chakster is your man, but he’s been away from the forum for a while. The simple answer to your question is that the bearing and the spindle shaft are what needs lubricating in a direct drive turntable. If you have purchased one that has not been s... 
Classic Ortofon Cartridges: The MC2000 MK II or the MC3000 MK II?
Raul and Edgeware you are correct and I was wrong in stating that 2.2g to 2.7g was the range of VTF for the MC2000. I was reading a table for the MC2000mkII when I got the info believing it to be for the MC2000. It seemed incorrect to me too, and ... 
Classic Ortofon Cartridges: The MC2000 MK II or the MC3000 MK II?
Yeah, don't think I own one, but I might.  Usually I am not one for test LPs. My question is really why, not whether it sounds good, although it does.

Dear Wally, From your excellent videos (excellent in terms of clarity and presentation), I get that when the line from the pivot to the stylus is perpendicular to a line drawn on the radius of the LP, there will be no tracking force. That is exact... 
Classic Ortofon Cartridges: The MC2000 MK II or the MC3000 MK II?
Good points, Raul.  Any thoughts on the surprisingly high recommended VTF (2.2-2.7g), for both cartridges?  My old MC7500 is tracking just fine at about 2.2g.  Before I finally looked up the recommended VTF, I set it at 1.6g, just based on my faul...

Timeltel, it’s great to hear from you. Hope you’ll stay around. what with all it’s problems, drawbacks, and impractical aspects, it’s a wonder how good vinyl can be.

Edgeware, In his original Stereophile review, none other than J Gordon Holt rated the MC2000 the best he had yet heard, while he also cited its problems (high cost and minuscule output). So I’d say the MC2000 put Ortofon on the high end map. There...

I think we’re talking past each other. But I’ll take a look at your attachment.  
Rega planar 8 : Tracking force and Anti-skate settings
“Crack”? if the LP is in such bad condition, I’d bin it before adjusting my tonearm to play through it.  
A new way of adjusting anti skate!
Dear Mijo, I never said the skating force was not affected by groove modulation. In fact, I agreed that it IS affected by groove modulation, which I described as “tortuosity”. My objection was to your repeated insistence that velocity or speed aff...
