ILD2-S Ultrarare CRT VFD indicator tube for DIY and education NOS Blue
I didnt found any information about this tube, but its not a much differents from its more young brother ILD3-S, so next information here: 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. 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.)
