"SETs in general are borderline AB - that is, while the output triode is never really cut off, its average current does increase with power."

Isn't that another way of saying that SETs generate a large amount of even-harmonic distortion? To the extent that the average current increases with the power output, this means that the current on the positive halves of the cycle increases disproportionately more then current decreases on the negative halves of the cycle.

That is, it seems to me, the essence of even-harmonic distortion.

If the distortion is so great that the average current draw is increasing significantly with loudness, then one is probably talking not so much about high fidelity reproduction as about sound effects.
