In many instances, the power that comes from the electrical outlet is unstable. This instability tends to affect the speed of many turntable motors. So it is quite possible that electrical power is one of the main causes for your turntable to run faster.
As mentioned in previous posts, there are other variables that also affect the speed of a turntable. The leveling of the bearing will affect the speed of a turntable in many cases. In this scenario, the weight of the platter plays a more active role. In my particular case, I set a calibrated PRO 3600 digital protractor on top of an Avid 45 adapter to level the platter bearing. The PRO 3600 has accuracy of 1/100 degrees. When my platter is perfectly leveled, speed accuracy of 33 1/3 is dead on. The platter will play at this speed for as long as the turntable is absolutely leveled.
If a turntable uses a bearing well with oil, as the oil dries out, one should expect the speed to slow down with it. Also, Many oils will change viscosity as their temperature changes. Since the bearing friction will increase the temperature to some extent, one can expect the turntable to go through some speed changes.
The Synchro is a power re-generator, so it will output whatever frequency you set it up to, regardless of the input frequency from the electrical outlet. What you're experiencing with the Synchro is normal.
