Post Subject: some factors in the potentialPosted by Dominic on: 1/17/2007
here's an extract from some people involved in such research http://adsabs.harvard.edu/abs/1989ITED...36.2651O
The miniature glass ones i mentioned, are called sub-micro and some examples are shown here: http://www.oneillselectronicmuseum.com/page10f.html. Still got to find some info though.
The micrometer size ones use Field Emmiters, like transistors, rather than heated plates like the usual kind of tube. I wonder if this is a good thing or a bad thing from a sound perspective.
