To forestall any armchair engineers, yes, this efficiency is System
efficiency...

.... which is not the definition of "plate (anode) efficiency"
from the IEEE Dictionary: "The ratio of load circuit power
(alternating current) to the *plate* power input (direct current)."
For amplifier efficiency calculations, only the DC power input
to the plate-collector-drain is considered, by definition. The
power dissipated in the surrounding support circuitry is not
included in the definition of "plate efficiency".
