GS-14

The GS-14 (ГС-14 rus.)generator triode in titanium-ceramic design with natural air cooling for operation in the centimeter and decimeter wavelength ranges. Designed to generate, amplify and multiply high frequency oscillations in the range from 300 to 4300MHz with an output power of at least 2W. Indirectly heated oxide cathode. It is produced in titanium-ceramic design with a plane-parallel system of electrodes.
