Pioneer PLX 1000 noise

I recently purchased a PLX 1000 from another Audiogon member, and it came in excellent shape.  My question, for anyone who owns or has listened to one of these, is have you heard a faint noise coming from the motor area?  It's enough to hear it from 10' away, although very slight at that distance.  

It is not a constant noise, but a slight chuffing noise that has a regular cadence.

The table sounds pretty good, but I'm curious about the noise...

Thanks for sharing your experiences.
