Re the NVS servo question : please read my posts more clearly.
My post of 02-04-13 explains that the term "17 degrees of freedom" used on the NVS website under the title "Speed Control" indicates they use it. I included an explanation as to why.
My post of 02-07-13 cites the Stereophile Review in vol 35 no 10. "servo controller with an active ultrasonic feedback loop"
If you want to believe black is white, thats fine, but please dont misconstrue my posts. Thank you.

Hi Richard
Holy Moly.
This being a TT thread will post a link in the appropriate thread :^)

Dover, Please lighten up. I am probably guilty of not studying your posts with the dedication that they deserve. Nor am I guilty of criticizing you if you might have been incorrect about whether or not NVS uses a traditional type of servo mechanism (meaning one where there is a device that directly monitors platter speed and feeds information back to a controller for compensation). You apparently inferred from the term "17 degrees of freedom" that they DO use such a servo. My error is apparently that I quoted you as having actually said that THEY say they use a servo, which perhaps is not the case(?) I am still not certain how the NVS works, but it is not a matter of great concern to me either way. As for "Stereophile Review", puh-leeze! I am sure you can find a better independent authority than that. As for believing "black is white", where did I do that? I am speculating, not believing.

Hi Richard, Albert Porter, Bill Thalmann
I came across your new website today.
As a hobbyist with no affiliation to any of you - congrats on the new site and good luck.

Thanks Ct0517, but I have nothing to do with the upgrades or the website but did lend my photos to Krebs since my table benefited greatly from the mods he licensed Bill Thalmann to do.

I've known Bill for a good while and always tell people he is the guy that did my electrical and Krebs upgrade work.

Even before this Technics stuff, Bill worked on my custom Dali (tube) crossover and greatly improved both the resolution and dynamics.

I thought I had reached the limit since this was our third version of the crossover but Bill suggested a small design change that required few parts and it REALLY worked.

I love recommending this kind of person to the community.

Just to clarify things. Albert Porter has no financial interest in the Krebsupgrade. I used photos of his plinths because he kindly allowed me to and because I think that they are really cool. Bill Thalmann is my appointed agent in the America's. He does great work.

Thanks.
