wow and flutter

I have recently purchased a rega 3 (planer) turntable,I have attempted to set it up as best I can with my modest resources, ie to reduce vibration etc. I have been lucky enough to be able to purchase a second hand decca stereo check up record (in good condition for a dollar) but the test that shocked me was the 3khz tone for wow and flutter.Is there any way this distortion can be reduced apart from a heavier platter.

Get a rim drive or quartz locked (linear) direct drive turntable. A lesser belt drive will always give you troubles. Don't feel bad, there's multi thousand dollar belt drive decks that will also fail that test!

Actually, music is way more complex than the test...

Seand, it's not all about torque--it's speed stability. That's why I mentioned *linear* when suggesting direct drive and that's why VPI uses flywheels in their top end belt drives. In fact, their top model uses two motors and one flywheel. Why not go for the simpler, single motor, 20+ platter approach that you suggest instead? Because
it takes more than 20 pounds. In my belt drive transport there's a weigh on top of the CD and that's enough once I had the power supply modded by Dan Wright--but in a turntable it's a whole different game. Think about it.
