If I were going to build with tubes again and two hundred watts was
the carrier output that I wanted. 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.

I'd like to build my own AM transmitter.
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....
