I'm hoping that the experiences of this group's members might help me with these issues.
I'm attempting to bring my Oracle Delphi I/II (serial #4675) turntable back to life. Years ago, I replaced most of the aluminum parts with the "Perfectionist Engineering" delrin parts, including the bearing. At the time, the technician said that the lubricant was very special because of the materials used in this bearing.

My first question is: What lubricant is safe to use in this bearing? I would like to do no harm, since I already shorted out the Lambda regulated power supply that I once used for this turntable.
That leads to my second question: Is there a reliable place that repairs industrial power supplies? While adjusting the power supply, I accidentally touched the part labeled "M 2N2405 252". This resulted in a big spark and a blown fuse. I've replaced the fuse, but it's not working. Obviously I've done more damage than that.

Thanks in advance.
