Tubes

No "branding", no registration required, no arbitrary limits to only so many datasheets, no stupid renaming them to the same thing for all of them so that someone downloading several needs to do more typing, no multiple layers of stuff to go through to get at them, and no cookies -- just pick a page, and click a link.

If you can think of improvements that I can make feel free to email me, I'm open to suggestions.

If you like what I'm doing and would care to contribute anything, be it cash (in any form), parts, databooks, or whatever, feel free to email me -- I could use all the help I can get at this point and all contributions of whatever size are gladly accepted.

I've opened a PayPal account to make that easier...

Notes:
Construction refers to both basing size and the envelope.
H/F means "Heater or Filament" voltage and current specifications.
(F) means "Filamentary", and (H-K) means "Heater-Cathode.
Numbers shown in light yellow background are used in series-string configurations.
Numbers shown in light blue background are cold-cathode tubes.
Numbers shown in light red are High-Voltage Rectifiers.
Numbers shown in light orange are power rectifiers.
Numbers shown in light green are for battery-operated radios.
Numbers may not show up where expected due to "combination" numbers -- e.g. 6CG7/6FQ7 -- if necessary use the browser's search feature (ctrl-F) to find them.
