Index of vacuum tubes is sorted in families by operating principles and applications. The collection is focused on American and British tubes for special applications, including types designed during early developments of radar and navigation sets. The new index lists about 1.000 special tubes. Some types may be listed in more than one family, because of their multiple usages.
