Halcro, I agree the test record has an eccentric hole, as do most music records, so the variation in speed from the effects of warps or eccentricity is there on all records to some degree, do you think this makes a mockery of perfect rotational speed? Perhaps Nakamichi was onto something with their record centring mechanism. I have posted screen shots of the Feickert test on the TS 700 with and without centring, and it makes a considerable difference! I suspect the variations detected by the test tone +- 2 Hz at 3150Hz, would be undetectable with the time line. Did Nakamichi make the "best" TT of all time?:)
Turnable database with TimeLine
Here is a database showing various turntables being tested for speed accuracy and speed consistency using the Sutherland TimeLine strobe device. Members are invited to add their own videos showing their turntables.
