Single Ended Triodes (SETs), the ultimate tube lovers dream.

RE: Ultimately...

Have you got a set of curves better than this? This is all I could find.

"Despite this, on paper 6P45S wired in triode is very, very linear and rivals many triode. Please "google" its curves and check it out."

The spacing gets wider to the left and narrower to the right.

The plate voltage changes 200 volts in one direction but it only changes 160 volts in the other direction for the same grid change. That will cause a lot of harmonic distortion.

That is not "very, very linear". It's not even close to what I would call linear.

A 45 is very, very linear. A 2a3 is very, very linear. Hell, even a 300b is very, very linear compared to what you have.

Linear is when the plate voltage changes the same amount, left vs. right following the load line, as the grid voltage is changed from the idle point.

Sorry, maybe you have a better looking set of curves.
