It's occurred to me that it's possible to create a software tool that will take the LTSpice model for a tube and create an optimal linear input-output load line. It could also be used to take a given load line and find the most linear load line position.
Has anyone done this already?
I was thinking of creating an Octave (free Matlab clone) tool todo this in a Jupyter notebook. Only issue is Octave is single threaded so may be a little slow.
If I create a 4096x4096 grid I can approximate quickly - not many people need more than 0.1V or 0.1mA accuracy so that would perfectly well.
Then it's a case of finding the flattest linear line across for the given Vg.

Not sure if this is what you're looking for, but useful:
