Hello all,

Recently, I have been working late at uni and have therefore had the 
chance to explore the piles of junk laying around. Last night I came 
across a box full of literally HUNDREDS of vacuum tubes. Most of these 
appear to be spares for our old x-ray diffractometer. Some of the tubes 
are quite large (over 8" tall) and are rated at 150kV DC. Now, I have 
no idea how tubes work or how to make a tube coil. What kind of tube is 
required for tesla coil use. Will any tube do? I am allowed to have all 
of these if I want them. I'm also allowed to have the old (from the 
50's or 60's) x-ray machine itself! I also found an old Hewlett Packard 
computer tape drive cabinet from the late 80's. It will make a perfect 
housing for the control circuitry for my pole pig.

Cheers,
