VPI SDS exact speed in .... 40 minutes?

Thanks for the responses. I use oil in the flywheel and the platter bearing, not grease. Do you consider that using grease will help?. By the way, my platter is the one that is half black acrylic and half aluminum.

will try that Peter

Peter, do you consider that maybe the problem would be something inside the motors? any idea how to verify if the motors are running ok?

Thanks for your offer Peter but Im in the opposite side: Florida.

Yesterday what I have done is run the platter with just one motor and then the other (bypassing the flywheel and one of the motors each time). What is interesting is that the speed is perfect since the beguining. That makes me think that is a flywheel problem, but honestly don't know how that happens: it runs smooth, no noises and have tried using grease and oil with exactly the same results. Any idea?

what Im going to try this evening is run the same test without the SDS and see what happens. What it is interesting is that I need to set the Hz in 58.1 to run the table at 33.33 in the SDS, and should be at 60hz or very close to that right?

Thanks Peter, just sent you an email to pbnaudio

Thanks Ack. After emails exchanged with Peter, one of the couses would be the thickness of the small belts that goes from the motor to the flywheel so I bought new ones. As soon as I receive them will post the results. thanks to all for your input.
