SME speed adjustment

I have been reading with much interest the thread about speed accuracy and the Timeline device.

I have an SME Model 10 turntable which has no speed adjustment on the motor controller. I use the KAB strobe and my table is fine, but I fear that if I have the chance to check it with the Timeline, and the speed is off, I will not be able to adjust it, so the exercise would be futile anyway. Currently, when the speed changes over time, I replace the belt, as SME suggests and this usually works.

Could someone suggest a method to adjust the speed on a motor controller that does not have such an option? Is there an aftermarket device that can be used to alter the voltage to the motor controller or some other method?

Any advice would be much appreciated. Thank you.

Agree with Ketchup,

Imagine the wall being 30 feet away versus only 2 feet away. The greater the distance to the wall, the more pronounced any drift of the Timeline dot from a starting reference point Simple geometry.

Halcro,

I see your point. I can't hear a tiny pitch deviation from 440 Hz. And I don't hear problems with speed changes during heavy passages due to stylus drag, so perhaps it is not an issue. I sleep well not testing with the Timeline, but these threads are starting to get me worried, perhaps needlessly.

I think the newer SME motor controller which replaced the older rectangular/front dial type is available for my SME 10 and it has variable speed. It seems this would be a simpler solution than buying the Walker or VPI. I will look into the new SME controller.

Can anyone verify this?
