indicator
Miniature electron-light indicator with an oxide cathode of indirect glow,
it is intended for setting indication in radio engineering devices of wide application.
The 6E3P lamp is made in a glass finger housing with 9 pins. Works in
any position. The cathode of indirect incandescence.On the side surface of the lamp cylinder,
along its axis, a strip of phosphor is applied.
