Sonic atributes ultralinear vs tetrode vs pentode

OK- here's my text:

Ultralinear allows the tubes to approach triode linearity, while retaining most of the power that Tetrodes (or Pentodes) otherwise make.

here's your assertion:

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

If we take 60 watts as being 100% of power, 40 watts is then 2/3 of that, or 'most of the power' as I stated above. I don't see that being significantly different from your position. Some hairs are in danger of getting really thin here.

Is "most" defined as 2/3?

Wish I would have known this in high school. Instead of telling my folks my exam score was 66, I could have said I got most of the questions right.

Damn

Atmasphere, "If we take 60 watts as being 100% of power, 40 watts is then 2/3 of that, or 'most of the power' as I stated above. I don't see that being significantly different from your position."

Your understanding is fatally flawed. I'm not sure whether the issue lies on the side of mathematics, logic, or language. This is not a question of splitting hairs, but rather a fundamental difference in statistical analysis.

What first needs to be recognized is that 0 is not one of the endpoints for a comparison between triode (20 wpc for the example at hand) and pentode (60 wpc). UL (40 wpc) is exactly midway (IOW, 50% not 66.67%) between the two. As such, the word "most" can never be used in such a context.

Again, how we got into this circle was your claim, "Ultralinear allows the tubes to approach triode linearity, while retaining most of the power that Tetrodes (or Pentodes) otherwise make."

If you simply took the position that you are personally fond of this particular compromise, I'd understand and accept it. However, steadfastly refusing to concede the point regarding the word "most" in your argument is analogous to mixing black and white paint (or, red and yellow M&Ms?) in a 50 - 50 ratio, then attempting to claim it has more than 50% of one of characteristics of black (or red), while at the same time possessing more than 50% of one of the characteristics of white (or yellow).

I'm not sure how else I can make the point, but a great many of the classical scientific laws dating back to the ancient Greeks have proven you can't get more out of something in this world than you put into it.

Ok lets try again...what are the sonic characteristics of the the different modes of operation?
Thanks

Despite the distraction, this still holds true.
