What is the mutual conductance, in micromhos, for a new 811A
supposed to be ?
I've also seen comments about sagging fillaments causing "short"
problems. I see in the RCA Transmitting Tube Manual that it states
the tube is to be mounted vertically, base down, OR horizontally
....ONLY with pins 1 and 4 in the vertical plane (puts the fillaments
in the vertical plane where there is much less chance of contacting
the grid). Makes sense.
