Questions about Columbia 9000 I am the new owner of a Columbia 9000, but i have run into a few issues.

The motor produces a periodic sound when running at the set speed, but not when accelerating or slowing down. What causes this and how do I fix it?

The spindle peg appears to hold the turntable at a very small angle causing the needle to rise and drop about a millimetre every revolution. Is this behavoiur intended? Will it damage the records?

How do i clean/replace the cloth on the turntable?
