Default 7377 tube also known as QQE04-5-what was it for?




I was hoping someone might know some specific applications, e.g.,
equipment that used it.


** In the early 1960s, the main uses for 960 MHz were professional,
industrial and military.

You might even have found one inside a satellite.

Not the sort of gear most folk ever see.
