The power supply I've design will allow you to plug directly into the back with your current line cord (for NA users, without an adapter) and use it. In this mode you will benefit from the ability to get the speed right and from the ability to optimize the voltage drive level. As the drive level is reduced the motor vibrates less, "communicating" less noise to the platter. This results in enhanced music resolution. However, to take full advantage of the capability of this supply to improve sonics, you will have to rewire the motor. Then you can drive each coil with a separate voltage supply, having then the capability of optimizing the phase shift between the drive voltages to minimize vibration further. The capacitor present in most turntable motor circuits does the phase shifting, but does so imprecisely, as each capacitor and motor is different with respect to manufacturing tolerances. So the capacitor must be removed and the motor rewired to accept to separate AC drive signals from the supply.
