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

RE: Dennis talks 2A3... post-RMAF 2016

I think we may be interjecting a bit too much into the accuracy of the sketches. It does appear clear that the anode area is directly related to the filament structure. In the drawings I referenced there are curves around the corner which seems slightly more plausible than the sharp angles shown for the 211. I do strongly suspect that the edges are much more softly defined and and the "boxiness" of the drawings represents the average behavior over an area.

The point I was trying to put forth was that the filament appears to define the "active" plate area and while 100% "anode activity" may be achievable, I am not convinced it is a figure of merit that we should solely base out tube choice decisions on.
