PS AUDIO P500 as a Turntable speed controller?

Analog Guru's out there:

Could I use the P500 Power Plant Regenerator as a turntable speed controller in my case? I am using the Michell Orbe SE - AC Motor with the larger PS not the newer DC Motors.

Its states by PS Audio themself that:

"Every Power Plant has always had the ability for the user to choose a frequency that best suits his systems needs, or perhaps used as a motor controller for an AC synchronous turntable"

Appreciate any advise or anyone doing this.

Have used an old P300 for over a decade on my Walker

How does Lloyd feel about your using the P300 on his turntable, instead of his own Precision Motor Controller?

Make sure that your P500 has the most current chip that adjust the frequency of the Power Plant in 0.0625 Hz steps from 50 Hz all the way to 120 Hz. If your P500 has the clean sweep feature, you should have the most up to date chip.

I used to use a P500 with my Naim Armageddon to set the speed 100% correct and spin at 45rpm (the Armageddon only does 33rpm). It also improved the sound of the TT probably reducing the motor noise and vibration. Make sure you get a unit that allows for small adjustments.

IIRC, the P500 needs to be set at 81Hz to achieve 45 RPM. I had both a P300 and VPI SDS when I was using a TNT Mk II turntable, and the P300 was substantially inferior to the SDS, sonically. when used to set turntable speed. But I think the P300 is a terrific power regenerator/conditioner in general (I'm now using two of them).
