Heh, I knew what was coming here and that it must mean you were in Canada (and only then checked the sender...) But all this seems like a red herring. Surely the three-phase power requiring devices only require three phase for the cooling systems? Wouldn't it be easier to just use a modern switching power supply to provide 5V and feed cold air directly from your home hvac and not try to run 50-year old cooling and power? -- greg
