In my 1964 handbook there is a One-Band Kilowarr Amplifier
that uses a pair of 813s. It is grid input and would be
easy to modulate using 811s or 572Bs.
In the 1956 handbook is a 500 watt transmitter using a
single 813 which would also be easy to modulate. It uses
the swinging link coil in the final.
Just interface a modulator from either handbook and you
would be good to go.
