GU-23A
Water-cooled high-power generator triode
Description
Purpose and application
GU-23A is a high-power generator triode for RF oscillation and power amplification in stationary radio equipment. Its documented applications include industrial metalworking equipment and radio transmitting systems, where a high-voltage RF stage is required.

Construction
The tube uses a directly heated cathode and a water-cooled anode. It belongs to a large metal-glass generator-tube class, therefore the mounting hardware, cooling circuit, working position and protective measures must match the exact equipment documentation.
Operating data
Published reference data give a heater voltage of 12 V and heater current of 195–225 A. At an anode voltage of 5 kV, anode current is stated as 7–12 A, transconductance as 42–56 mA/V and gain as 42–57. The maximum operating frequency is 26 MHz.
Cooling and selection
Maximum anode dissipation is 60 kW and maximum grid dissipation is 2.6 kW. These values require a designed cooling and power system; they are not commissioning instructions. Before ordering, compare the exact marking, electrodes, cooling fittings and passport data of the offered tube.
Vacuum device construction is outlined in the vacuum tube reference article. Related products are listed under generator and modulator tubes.
