RE: Not to beat this thing to death but can anyone address the pentode ?

It's a beam power tetrode, not a true 3 grid pentode, but that's essentially semantics.
Max. open loop linearity in full pentode mode is obtained by regulating g2 B+ at a fraction of anode B+. Nasty IM distortion gets held down.
