Duncan Munro's TDSL (Tube Data Sheet Locator) is by far
the best source of valve data on the internet. This search engine
provides direct links to valve data on many of the other sites
listed here. Also take a look at Duncan's site which has a
lot of other interesting stuff.
A really huge collection of valves, arranged by country of
origin. Many examples of rare early types. English and German
versions are present but the German is more complete but still
under construction.
(English version) The English version is not yet complete.
The German version, accessible from the linked page is more
complete. Mostly Continental European valves, many modern.
Contains a useful search by category.
A page of old valves. See also the main Mike's Electric Stuff
pages for lots of other stuff including Crookes/Geisler
tubes, Nixies, Tesla coils etc. etc.
