Output impedance is something that's rarely quantified for high power RF

Output Z is dynamic -- that is, a function of the tube's operating
parameters AT POWER, under load, which those of us who learned 60 years
ago, could be computed by the "load line." It cannot be measured with
small signal instrumentation.
Jim, by any chance do you have any articles covering that? I've done
calculations of operating conditions from Rl and load line (and vice
versa), still got an Eimac tube computer somewhere, but I've not come
across anything relating to output impedance. I'd be very interested in
that.
Thanks and 73,
