This lot is for 1 ULTRARARE USSR VFD CRT indicator tube.
Type ILD3 (ILD3-K = red, ILD3-L = green, ILD3-S = blue) is a small cathode-ray tube without focusing system and beam deflection. It's just a point of light.
These tubes were designed for giant TV panels and scoreboards. As far as I know, only one such screen has been assembled in the USSR.
Each pixel of the screen consisted of four indicators ILD3 - red, blue and two green.

Indicator can adjust size of DOT, depends on modulation and 1st anode voltage, on the youtube you can look how it works
NOS, OTK(quality control)
The main electrical characteristics:
Heater voltage, V ................................... 6.3
Heater current, mA, nominal ............................... 100
Anode voltage, V ................................... 6000
1st Anode voltage, V...............................40
Current anode uA nominal ............................... 350
Modulator voltage, V ........................ 0 - 35
Voltage cathode-heater .......... + - 135
more information you can see in datasheet.
(I was connect about 6kV to anode, 24V to 1st anode and for modulator, 6,3V to heater and it works perfect too.)
