Description 6E5S Electronic indicator light. It was used for indicating tuning in radio receivers, radio stations, recording level indication in tape recorders. Now it is successfully used for signal level indication in tube ULF. Indication is carried out by a circular sector of green color through the canopy of the cylinder. Lamp parameters 6Е5С: (nominal mode) The filament voltage (serial / parallel connection of the filament) is 6.3V Heating current 300 ± 25mA Anode voltage 250V * Crater anode voltage 140..250V The bias voltage on the control grid -4B Anode current 5,3 ± 1,9 mA Current in the crater chain 5mA The steepness of the characteristic is 1.2 ± 0.4 mA / V Gain factor 24 The voltage on the control grid at the angle of the dark sector is not more than 5% -8.25 ± 2.25 V Color of glow of a crater green Dimensions Ø32,3х101mm The minimum operating time is 500 h Octal socket with key 6pin
