I bought a custom made power supply from Taylor House in North Carolina but that was over 10 years ago and I do not know if he (Robert Taylor) is still in business. It made a noticeable improvement in the bass and dynamics of the 'table and it had an on/off switch. The power supply was not made by Taylor House, but by one of their customers. I just sold my Oracle to the Stereo Trading Outlet in Jenkintown, Pa. You may want to ask if he'll sell the power supply separately. It may not be as good as the above, but should be a little cheaper. Good luck.
