Default Duty factor for Drake L-4B
Before I read Jeep's response, I was getting ready to respond that 400 watts
of output is right. Solder melts and things fail. I think that is a
realistic number.

It is not the tube plate dissipation that is the limiting factor. It is
heat - both from the components and from the currents flowing through the
switch contacts and the coils.
