[sdiy] DIY Electronic Components and Tubes 101

[laxt57 at aol.com]

Hi 
 Fascinating stuff! Did any one read the sections on homemade
valves(tubes)? Wonderful! In the first section he describes making
a high-vac vacuum gage, just spot on, that is one of the ways it is done. Although Mr.Steiner did let the filaments go to air the tube still operated. 
If any one tries this flood the evacuated spaces with nitrogen or other inert gas.
Think I will get my Varian vacuum pump out of its case and look around
for some old auto tail lamps. Maybe a sdiy valve synthesizer with sdiy
vacuum tubes? Another project.

That "someone" is Nyle Steiner, inventor of the EVI/EWI wind controllers and of a certain early VCF that has been quite popular around here lately.
