But WLW ran 500KW of 100% AM modulation. I understand just the
modulation transformer was the size of a room in order to handle the 250
KW of audio. I believe it was on 700 KHz. See the link I gave above.

The modulation transformer at VOA's Bethany relay station (located quite
near WLW's Mason, Ohio transmitter site) took up much of a very large
room. If you stood in that room, you could hear the transmitted audio
from the laminations. The sound was so loud that it was necessary to
shout to be heard over it.
