Powerful generator triode GU-23A with a tungsten thoriated, carbide directly heated cathode and water-cooled anode.
Designed to work as an amplifier or generator of high-frequency oscillations at frequencies up to 30 MHz in radio transmitters and industrial generators for high-frequency heating.
Decoration: glass-metal.
Operating position: vertical, anode down.
Forced cooling:
- anode - water at least 120 l / min;
- channel outlets - water at least 2.5 l / min;
- mesh output - water at least 2.5 l / min;
— legs — air not less than 80 m3/h;
- cylinder - air at least 100m3 / h.
