I recently acquired a Kenwood KD-5066 DD servo controlled turntable, and have been noticing a very slight variation in its speed. I will dial in the exact speed via the stroboscope, but over the course of a record the speed will shift ever so slightly and the stroboscope will slowly begin creeping forward or backwards.
The variance is far less than what I can sonicly detect, however I like many of you can get very obsessive about this sort of thing. Is this behavior normal for a servo controlled turntable?
Also, I notice a detector arm (presumably for speed) that is meant to be triggered by a pin on the bottom of the platter, however the pin never actually triggers the detecting arm, instead passing it slightly. It is not used by any of the automatic functions and I suspect that the motor may be slightly misaligned causing the pin to miss the detector. Could this be a cause of my speed issues if they are in fact an issue?
