Atmasphere, you've done nothing to address my refutation of your quote regarding Ultralinear operation giving "most of" what both triode and pentode offer.
As I initially said, the subject at hand represents yet another case of simply splitting the difference between two endpoints, as opposed to getting more out of something than what you put in. The world just doesn't work any way other than that.
If you compare an amplifier running in the three modes, if triode put out 20 wpc, UL would do 40, and pentode 60. Those figures work out in the absolute linear, proportional, and expected manner. In other words, again, your assertion, "while retaining most of the power that Tetrodes (or Pentodes) otherwise make" is untrue. "Ultralinear allows the tubes to approach triode linearity" would not be an incorrect statement in and of itself. But in the context of your position inferring it goes beyond the proportional and expected distance, it is.
"Rule the day" means sales/volume...
