Yes, I have said so about a half-dozen times now.

When you say that source impedance is a "variable", do you
mean this for a "typical ham transmitter", ...

Yes, the discussion is about typical ham
transmitters - nothing else matters to typical
hams.

Which results have been disproved on the bench?

Please research the grand argument between Warren
Bruene, w5oly, and Walter Maxwell, w2du.

Are the experiments documented in Reflections chapter 19 and
19a representative examples?

As far as I know, the Bruene/Maxwell argument first saw
light in a QST article in the early '90s and has been
raging ever since.

My read of these chapters is that they offer compelling
argument and evidence (at least for the tube style
transmitters examined) that ham transmitters are linear*,
at least over their normal region of operation.

Linear is not the requirement for your source impedance.
Constant, fixed, and linear is the requirement for your
source impedance. Nothing you have presented had the
source impedance as a linear variable.
