Anyone interested in our developing an AC motor controller kit for single and possibly three phase AC turntable motors?

 Interesting..a tentative "yes" Vote

I don't know much about these, so forgive me...would it include some kind of platter speed measurement info fed back to the controller?And a basic display of this info?

Would/could it include an actual motor too?

I could be depending on how flexible the design is.  May motivate me to build up an Empire.

Maybe, I have SOTA and VPI tables that may benefit but I really don't understand enough about it, time to do some homework :o

Yes, Merrill mod AR XA here.

Suggestion to make it have adjustable so it may be used with tables with 115 line voltage motors and also low voltage AC motors.

There is a new 12V AC motor mod for my AR. A motor controller that could handle both the stock 115 volt motor and the new 12 volt motor would be kewl.       

Some Pro-Ject/Music Hall tables have 16 volt AC motors too.

Hmmm, won't be of any use with my Clearaudio, but I do eventually plan to upgrade to either a refurbed Thorens TD-124 or a Kudzma Stabi-S / Stogi-S, and those would benefit.

Where was this idea 2 years ago when I bought a P300? 

Seriously now, I think it is a capital idea!  If I didn't already have the P300 I would assuredly be in on it.
