<<< < The best win is that 400 Hz power transformers are very small. ---------- I once worked on a military HF transmitter that could be operated off either 60 or 400 hz depending on what power supply was installed. The 60 hz supply came in its own 19" enclosure and took two men to carry. The 400 hz model could be held easily in one hand. BTW the 60 hz power used by the navy on board ships is different than what you get from your local utilities. It comes as two hot leads balanced at 55 volts to ground instead of a hot and a neutral. You have to be careful about what you plug into it. John Eaton !hplabs!hp-pcd!john
