    I thought most of that stuff was 400Hz? We used to have 60~400Hz 
motor-generators on ship for our computers. I have a notch in my hearing 
right at 400Hz courtesy of those mogens.

As a youngster I bough a lot of WWII surplus and some of it had high freq
dynamotor power supplies.  They wee usuall thrown away and we would home
brew a power supply.
