RE: Is there any real benifit sonically between class A, AB etc...

Well, it is not a static system, unless there is no signal applied to the grid, and so I can imagine emission densities higher in areas where the heating is more efficient and uniform and the extraction therefore being smoother and more linear when it is directly heated.

Just trying to think about it mechanistically as if i were an electron being emitted :).

I could see also maybe that a direct heated filament is hotter towards the center of the length of wire and maybe then the electron dispersion is different...there might even be some literature on this somewhere (probably too old to be on the web though). I bet some old East European tube guys have some idea.
