If we are posting specs, the following are some of the specs for my Teres Certus turntable (in my case the model 450):
My turntable has 60+ pound lead shot loaded platter to the best of my knowledge made of Cocobolo outer wood with a phenolic core
It has Low cogging multi-phase permanent magnet synchronous direct drive motor with:
1) Magnetic damping via eddy current brake
2) High torque capability (563 oz/inch)
3) High resolution digital drive signal synthesis
4) Speeds Supported: 33-1/3, 45 and 78
5) Speed Accuracy:
* 33-1/3 RPM: -0.011% +- 0.003%
* 45 RPM: -0.006% +- 0.003%
* 78 RPM: -0.160% +- 0.003%
Chris Brady does not have wow and flutter measurements for the Certus Turntables but has suggested that they would certainly be substantially less than 0.01%. I do not have any Rumble data.
