Description

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.
