I like http://www.tatjavanvark.nl/tvvd/viewer223.html . I have that tube and bits of a radio (original) that uses it. That tube is interesting: it's the world's first integrated circuit. Yes, a hollow state integrated circuit. I describe it that way because it is a complete subsystem (in this case, a complete 3 stage audio amplifier) rather than just something like a dual-triode tube where the connecting components are still external. paul
