I am no expert, but can linearity be independent from operating points, primary load and power output?
Would a 2A3 at classic operating points and 2k7 load be more linear/ less distorted as a 300B at 60ma/350V loaded by 6k? At 1W? At 3W? How about at an attempted 6W?
Just wondering?
Cheers.

I look at it from the standpoint of a voltage amp.
Constant current source loaded. A horizontal load line.
That's the best case for any tube in terms of harmonic distortion.
The published plate curves show that the 2a3 would have less harmonic distortion within it's capabilities.
But you're right, a 300b making 6 watts will do so with less distortion than a 2a3 trying to make 6 watts.

As you know, I am currently running 2A3s (and/or maybe 2.5 filament 300B?) - so no horse in the race, so to speak.
Cheers.
