Nope, E-models never had any wired 60Hz power. Anything with a motor or transformer that runs off 60Hz will operate on 400Hz, BUT, for a very, very short time.
Most of the test equipment runs off 50-400Hz now.
USAF OMEGA systems didn\'t use it either. I don\'t even remember a cooling fan for it, but I\'ve slept a couple times since I worked on that system.
