    Unit plays, but the stylus is picking up rumble from the motor.
    Direct-drive unit; all's quiet until the stylus lands on the record.
    It's quite pronounced if listening through headphones. Tried using an
    isolation mat & playing w/ the platter mat upside-down; no dice. Is it
    possible that I may need to re-lube the motor? Other ideas?

    Filter the input to the drive coils of the motor, or even
    make circuitry to supply sine-waves to the coils.
    That should reduce motor-rumble quite a bit.
