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.

I have used a PS300 for years as a TT speed control. From my MS BL-91, VPI and now with my Basis Debut with no ill effects. Very stable. Make sure it has multiwaveII for finer adjustments. Do not use the dual feq option, A/C motors do not like it, they can & will fail if used.

Quiddity,

This is directly from the PS300 manual.

Any turntable or equipment with AC synchronous motors, such as some cooling fans should not be used with MultiWave II+. This equipment must be used with 60Hz
SineWave mode. End.

What I am saying.
Use it in the single sinewave mode not in the multiwave mode if you are going to use it as a speed control for a TT. You can adjust the single sinewave, voltage and or fequency with an a/c motor with no ill effect. It is best to start at 60Hz and adjust from there.
With the PS300 multiwave you can emit more than 1 sinewave at the same time and that is not good for an a/c motor. In multiwave mode you can and will destroy your TT motor.
