Tubular Eye Tube
The 6E5 Eye tube is a glass Vacuum tube type used to
indicate visually by means of a flourescent target the
effects of a change in a controlling voltage. It is used
as a convenient, non-mechanical means of indicating
accurate radio-receiver tuning. In other words it shows
radio signal strength coming into the receiver and tells
you when you are receiving the maximum signal capable
with the antenna you have. This tube requires a
6-contact socket.
