I know this is an older post, but in the event anyone wants to do this, I have the article from 10th edition(1946) West Coast handbook with this circuit in it.

I would use a pair of 812s in push pull class C and modulate with a pair of 811As push pull class B. Run about 1500 volts @ 200 ma for 300 watts plate input on the 812s. Find a Modulation XFMR to match the output of 811A class B (about 12500 ohms as I remember) to the 7500 ohm class C final.

Tube style; more than 200 watts. Sure a heck of a lot to choose from...but I'd like to hear what you think. OR...if someone knows of a home brew for sale....
