Update on my power supply failure.
When I opened up the failed power supply, I found that the input side of the high voltage transformer had shorted out to a near by capacitor. I opened the new power supply and found that the line followed the same path. I insulated the capacitor and line with kapton tape. I then added some non conductive foam between the problem areas. A quick inspection of the failed power supply also showed that the output line was rubbing on the power supply case. I made sure this was also isolated on the new power supply.
@donkjr The power supply failure was not related to the oil from the refrigeration compressor in the cooling water.
Everything is working good as new. (as it should!)
