Cool article that Google doesn't find easily

[Windcrest77]

Just linking another very cool article to the group. Buried deep in the bowels of some server at the University of Denver I found this. I would have liked to learn about tubes from this teacher, Elizabeth Tuttle, she has to be in her 80's by now. She taught at the University of Denver. This article nails it on anyone wanting to learn about tubes without getting every formula plus the kitchen sink thrown at you. She has you first create some curves manually before the experiments, very cool, old school like how they did it before computers and Spice.

I dont know what the hell I'm doing about a lot of things! But somehow this article has helped me a lot to get to a place where all the junk on my breadboard starts making some sense, especially the experiments section and triodes.

Thanks!

The article will certainly boost my knowledge of phanotrons, kenotrons, pliotrons, thyratrons and compactrons!

I had some similar to it in other places, including same drawings and typography.

I like to make my designs following the old school method, simulators I use rarely and as a pre-check only, and I have not much confidence to them.
