I read several threads where some replacing the motor on their AR XA turntable but I could not find a definitive answer for those of us who own the early XA model with two motors.
My turntable works and spins at the correct speed, my problem is that I can hear rumble during quiet passages. I hear the motor/motors turning or operating through the speakers.
I would be willing to run the table with just one motor, it's a beautiful piece which I even adapted a hinged dust cover.

What does the vinyl engine recommend me to use to make the turntable as quiet as possible?
