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.

That Kuzma is a nice table!

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.

Grainger,
I was just doing a bunch of research on power plants and conditioners andthe kind of control unit doc is talking about is far more accurate than the voltage regulation tolerances of even the best power plants.
Actually it's a different animal altogether as this kind of motor control regulates and allows for very fine adjustment of frequency whereas power plants are mostly designed for voltage stability -- and the PS Audio units seemed to have the largest voltage swing/lowest regulation tolerances -- 5% vs 3% for companies like PurePower.
I actually settled on a completely differentapproach -- an Equitech balanced power center -- no voltage regulation to speak of, but real, honest-to-goodness professional studio quality balanced power.
But if you are not jhaving any issues with speed control, the ps300 is probably good enough.
Another use for the kind of thing Doc is talking about is for 33 to 45, or maybe even 78 rpm switching without belt and pulley changes -- just turn up the frequency to get higher speeds. BPI used to make the PLC (which I used to own) which did sort of the same thing, and they also make the SDS -- synchronous Drive System, which is what it sounds like Doc is talking about here.
HTH,
Jim
