You said "Think of the "draw" current as a one-foot diameter snake going down thru a 10 foot wide hallway. No problem! No?Then, the snake swallows a nice, juicy 40 foot diameter morsel. That is our pulse-- as in amplifiers and music."
That pulse is a current increase. That current increase does not ever get bigger than twice the idle current. If it does get bigger than that the whole gig is up because you are no longer operating the amplifier in a linear manor so who cares? In your amplifier, that you rate at 1 watt, the current increase will be even smaller.
So whatever you are saying about "the pulse behavior of materials" are only important to a current value of no more than twice the idle current not some huge current "pulse" that you are imagining.
On a different note,
Dennis, will you ever finish this discussion?

You said;
"You won't get more "oomph" from any 2A3 by running more than 45 ma. It doesn't work that way. *When the tube is not run as hard (as the standard 60 ma.), it can stand far more input swing without distorting*."
Speaking only about the part between the **, I say that you are dead wrong.
When we got to this point in our conversation you just stopped.
Why? Is it because you don't have an answer?
It's very rude to just stop in the middle of a conversation Dennis.
If you decrease the idle current, without increasing the plate voltage and increasing the load impedance (as you have done in your design), the tube will reach clipping (distortion) SOONER, not later.
[ What I'm saying here is that you lowered the idle current and you didn't increase the voltage or the load impedance]
I can prove this to you but all you have to do is look at a load line on a set of plate curves and you will see for yourself that as the idle current is lowered (without changing anything else) the right side of the load line dips into the non-linear region (and cutoff) sooner, not later.
Please correct this mis-information that you posted.
