Subject: ARchive of tube specs?

Hello everyone,

I recently got an idea of starting to scan specs-sheets of tubes and put
them available to the 'net. Here I mean tubes that are of use for HV
work/hobbies - triodes/tetrodes/thyrathrons/ x-ray/ignitrons/etc. - and
are rare to find. 

I do have specs for some tubes (like H2-thyrathrons, tri/tet-rodes etc.)
but the amount of specs is not _that_ great.

So, the question is if anyone out there is willing to join the effort? I
don't know any archive like this (*HV*-tubes) on the 'net so this would
VERY useful for us all.

My plans include scanning the specs sheets to JPG pics. That way the
filesize will be rational and JPG is a universal format most programs
read and comprehend. Postscript, where applicable, will be used as well. 

Within a week there shall be specs for:  
H2-thyrathrons : 5c22, 5948a, 7322, 8503b, 8553/ku-72z, nlcx1140,
thyrathrons: f189, f205, f207, f211, f246 
triodes: ax125/2000 
tetrodes: ax5184, ax5186 
available at ftp://nic.funet.fi/pub/sci/electrical/tubes/..  

Later I add (mostly) Philips data sheets on old xmitter (power)tubes -
radioclub at university has these databooks. I may add specs on x-ray
tubes (mostly medical with rotating anode) as well. 

SO: Anyone out there with spare time, scanner and specs-sheets?

Please, reply via e-mail.
