The so-called g3 in this sort of tube is actually a beam concentrating set of plates. Beam tetrode is the correct term, as the electron concentration has the same sort of effect as hanging a third grid at ground potential, known as the suppressor grid in between the screen grid( g2 ) and the anode.
