This analysis doesn't include any parasitics, such as Miller capacitance.

Um, assuming that neglegable AC current flows from the grid circuit into
either plate or cathode circuit, and that the B+ rail has low AC impedance,
then, being a series circuit, how could the AC voltages at plate and cathode
be different, again assuming Rp and Rk are equal. I am also thinking that,
in this case, miller capacitance would not matter either as long as no
significant AC current flows through it.

Miller capacitance isn't the only possible parasitic. I just mentioned
it as a "for example". And, of course, no parasitic capacitance would
matter as long as no significant current flows through it. That is the
problem, to determine whether there is significant current in any
particular parasitic.

But, there will definitely be parasitics connected to the outputs. See my
newer analysis for that.
