Single-beam tube 11LO5V with one post-acceleration stage. with blanking plates, with a rectangular screen with a flat surface and a parallax-free reading scale.
Designed for visual observation and measurement of electrical processes in radio-electronic devices. The screen glow color is yellow-orange. The size of the working part of the screen is 60X80mm. The width of the focused line is no more than 0.6 mm.
Electrode leads: 1, 14 - heater; 3 - cathode; 4- first anode (focusing); 6 – grid; 7- second anode; 8 - fourth anode; 10 - third anode; 11 - blanking plates; 13 - modulator; X1, X2 - temporary deflection plates - side terminals on the cylinder; Y1, Y2 - signal deflection plates - side terminals on the cylinder; A - fifth anode (side terminal); 2, 5, 9 - do not connect.
