I believe that the lower 25 hertz frequency required heavier transformers that for use with 60 hertz power. 400 hertz aircraft devices may have gone to a higher frequency to cut down weight. Can anyone clarify this? Also I suspect that a heavier 25 hertz device might work OK at a higher frequency, say 60 hertz. But not possible to go in the other direction.... Brian
