I assumed that the blue glow was from some sort of ionized gas, but I also assumed it was there on purpose. I suspect it is one of the inert gasses, but I dunno. Sure is nice though.
The Sophia tube sounds interesting. It also sounds like it is neither 300B or 2A3, but rather a third that shares some characteristics of them both. Sort of in between as far as bias and load line goes. Interesting.
