[Amps] again

This gets perilously close to igniting that argument about whether or not you provide a conjugate match to the tube. Since most linear amps are around 50% efficient, the answer would appear to be 'yes', although not intentionally. Something I've never figured out or had explained to me is how you can have much higher efficiencies than 50% if you do achieve a conjugate match.......So I've always gone along the route of providing an optimum load impedance.
