Last night I finished reinstalling the power supply in its new half-rack home. The power entry is fused at 20A, the big Variac is connected, the wires safely routed around the HV supply; still, there is only one power receptacle that the regulator and whatever auxiliary items must share. It was just too inconvenient to somehow plug the regulator into an internal receptacle so near the HV poles of the supply. I'm going to make a sign reading something like, "Do not unplug this cord until supply has been powered down for 60 minutes."
I switched on the affair with my big toe, my fingers firmly inserted in my ears. No bang, boom, or fizz. I cranked up the Variac to 1000V, as shown on the input voltage meter. It looked perfect and I switched it off with my right index finger.
