Types

We could do with illustration of the different types / styles. Tabby 18:53, 2 December 2007 (UTC)

Used before invention?

Quote: "...It is also called cat's eye, or tuning eye tube. They were fitted on radio receivers from around 1936 onwards...Invented in 1937 by Dr. Allen B. DuMont..." ? --Glenn (talk) 23:51, 27 December 2010 (UTC)

Wrong legend?

The first picture in the article doesn't show a EM11 tube, which should have four sectors instead of two - similar to a Maltese cross. The depicted tube most likely is a EM4, EM34 or something like that. Menrathu (talk) 17:52, 19 December 2014 (UTC)

This data sheet would indicate that you are correct. --Elektrik Fanne 16:01, 29 May 2016 (UTC)
