Just purchased a new Gem Platinum turntable

For those with motor noise on these tables. . .if you experience this with belt drive, then the motor may be the issue.

If however, the noise is only present in rim drive, then you have the motor too close to the platter. This results in "torque" on the motor shaft, and produces noise. The drive ring should barely contact the platter. Try moving the motor pod away to that point and see if it makes a difference.
