ILD3-S / P590 Ultrarare CRT VFD indicator tube for DIY and education NOS Blue
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 video, you can see it: Also, you can drive indicator by magnetic field
- Ultrarare CRT tube with blue glow
- 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
- (I was connect about 6kV to anode, 24V to 1st anode and for modulator, 6,3V to heater and it works perfect too.)
