Description
Generator pentode GU-46 with a directly heated tungsten carbide cathode in a glass shell and natural air cooling. It is designed to work as a generator and amplifier of high-frequency oscillations at frequencies up to 60 MHz with an output power of at least 700 W.
The GU-46 pentode is used in generators with independent excitation or self-excitation, as well as for linear power amplification in radio transmitters.
Stamp of technical control department of the manufacturer “ ОТК “
GU – a letter that determines the type of lamp: GU – generator lamps with a generation frequency of 30 to 300 MHz; 46 – the number of the serial number of the development of this type of tube.
Working position – vertical, a socle down. Cathode tungsten thoriated carbide direct heating.
It is produced in a glass baseless design with 7 pins.
