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.

I am in the thinking stages of my next rig and would like
some ideas.
I am thinking of a pair of 813's or maybe even 4-250's but
I can't seem to find any specific plans or designs on
line.
There must be lots of them out there.
I found a thing called the 813 Maul which is 813's
modulated by 813's but that is the only one.
Any help? Any other ideas?
