I guessing as a regulated power supple. In any case, i bought a Nottingham on the strength of a Paul Seydor recommendation in TAS part of which said that since the motor was so weak as to be started by hand push, the power line fluctuations wouldnt affect it. In addition his description of the characteristics of the sound produced by the table and arm were those that I wanted. Great table and arm with a Dynavector 17D3 cartridge. In a post here I saw that someone had a Wave Mechanic motor controller made by Nottingham for sale at a good price and bought it. BIG improvement!!! Even in a place (Clemson, SC) that didnt have power problems. I suspect that motor controllers would work very well with any table as long as it were a good one- the better the controller the better it would work.

But there are motor controllers ... and then there are motor controllers ! :-))
You said (I'm paraphrasing!) " I guess they act as a regulated power supply. " My understanding is that they basically work like this: AC mains converted to DC (for the one I use, this is 48v DC) ... which powers a chip which generates a 50Hz sine wave (60Hz, in your case, being in the USA). So I guess this means the output is a solidly regulated AC wave?
Interesting that you found the TAS "recommendation" was BS and that a good motor controller did deliver a sonic improvement on your deck! :-)) Can I suggest you get hold of a small isolation transformer and put it between the motor controller and the wall mains supply ... my recent experiments have shown (on each of 4 different TTs - including one with a DC motor & controller) a significant sonic improvement from using the 'Isotran'. This is rated to deliver 250ma of current (at 240v) so it is 60VA - at least double what the motor controller consumes.

When I had a Nottingham Ace Space Deck, I bought a used VPI SDS and yes, what an improvement it made. One thing I found was that at idle, plugged in, it was normal for the motor to vibrate, it vibrated less when plugged into the SDS. Background blacker and attacks and dynamics improved.

I suspect that motor controllers will work only with turntables using AC synchronous motors that are directly powered from the mains waveform. Perhaps this is the norm today, but I haven't owned such a turntable since my original AR turntable over 40-years ago. My Thorens TD-126 Mk III had a servo controlled DC motor. My Denon DP-62L was servo controlled direct-drive. I had a Dual 505 many years ago that might have run off the mains waveform but I don't remember. My Sota Millennia Vacuum has its own built-in motor controller and my Technics SL-1200 Mk2 is quartz-locked direct-drive. Therefore, I think it depends on the particular turntable as to whether it would benefit from a motor controller.
Best regards,
John Elison
