Hi, I'm also having the exact same issue, but I'm afraid I have nothing much to offer to you apart from some info on things I've tried myself to isolate the cause. I double checked the motor retaining screws had been removed (so the motor is suspended with rubber bands). I even ordered the pro-ject oil for the spindle bearing / well. The noise has improved very slightly but it's still there (or I'm suffering a little from the placebo effect!) It does seem the vibration is transferred down the belt though like you say- remove the belt no noise (I even ran the motor with the needle placed onto the base- noise only comes when the belt is in place- which suggests to me the vibration is transferring down the belt into rotating parts.
