Such tubes include x-ray tubes, radio transmitter tubes, switching tubes, pulse tubes etc. The common thing about all the tubes is that they are of great use for an amateur with interest to some area of physics/electronics - and the specs have been difficult to acquire until now. If you do have some old tube manuals and access to a scanner, please, do contribute to a good cause and upload the scanned specs to incoming directory. Send mail to the address above and notify the maintainer what you have uploaded - tube TYPE is important. The common way for filenames is to use the tube name as the first part and then _1, _2 etc. for each scanned file of the same tube. For example ax5186_1.gif, ax5186_2.gif, .. , ax5186_4.gif.
