There are, of course, other factors contributing to “wows” such as spindle eccentricity,
turntable wobble, vertically and record groove eccentricity with respect to the spindle.
Many times, rotating the turntable 180
°
with reference to its original position on the
spindle will help decrease the amount of vertical turntable wobble.
All of the above tests should be made with only one recordon the turntable, since record
slippage if two records were used, would give misleading results.
The bearings of the motor should be checked to see that they are properly lubricated.
