If you do decide to go for a PS unit, instead of the Wave Mechanic I would suggest the new PS from K&K Audio. It will require rewiring of the motor pod but that is relatively simple. This PS supply has separate outputs for each of the two field coils of the motor (the capacitor is removed from the pod). The unit allows one to tweak the phase angle of the AC current between the two field coils to minimize motor vibration. The level of the output voltage can also be adjusted. I found this to be particularly useful in improving the sound. The parts used in construction are of very high quality. For example, instrument grade OPA chip amps drive the two toroidal output transformers. I sold my Wave Mechanic. This new PS was noticeably better.
