Ye3s but the cost of a good modulation transformer for 300 watts or more
would be as much as a SB200. Actually for a good rig you could run a pair of
813 or a high power triode similar tube at about 800 watts and cathode
modulate at 400 watts. This is cost effective and works well. Tetrode tubes
do not cathode modulate well.

Healthfully yours,
