Indeed... that's why they are expensive (new.. not surplus)

400 Hz means you've got to have very thin laminations to cut eddy current
losses
40 Hz means you've got to have a lot of core area.

No wonder everyone likes switching PSUs... power line, bridge rectifier,
capacitor, then the switcher running off the DC bus.
