Jfz, There is no way to change out the NEMA that I know of, unless you can get in from the back. Maybe you could use an adapter. Shunyata says that if there is a problem with an original Hydra, they would have to break one of the sides, top or bottom to get inside the unit---it is a permanently sealed piece. Very elegant looking though... I thought about sending mine in for a checkup about a year ago. You might be able to get the nema out, rewire, and put in an IEC, if the IEC is about the same size and shape. My original Hydra has been a permanent part of my system for about two years. I'm using a Shunyata Anaconda Alpha Helix with mine-- It's very dynamic, musical and has good separation of instruments.
