Description

Powerful generator tetrode GU-35B in a metal-glass design with an indirectly heated oxide cathode and forced air cooling. It is intended to operate as an oscillator or a broadband amplifier of high-frequency oscillations at frequencies up to 250 MHz with an output power of at least 2 kW. The tetrode GU-35B is used in television transmitters. Works in a vertical position.

Forced cooling:
– anode – air at least 400 m³/h;
– legs – air at least 100 m³/h;
– cylinder – air at least 60 m³/h.

Stamp of technical control department of the manufacturer “ ОТК “ 

GU – generator tubes with a generation frequency from 30 to 300 MHz
35 – the number of the serial number of the development of this type of tube
B – indicates the type of forced cooling, B – air.
