GS-35B (original box)

Generator triode GS-35B in ceramic-metal design for operation in the decimeter wave range. Designed to generate and amplify the power of high-frequency oscillations in the frequency range up to 1000MHz with an output power of at least 1000W.

The GS-35B triode is used to generate oscillations in self-oscillators with external feedback and to amplify power in a continuous mode in circuits with a common grid in radio engineering devices for general and special purposes.

It is produced in ceramic-metal version with external anode. Cooling forced air.

GS – letters defining the type of tube: GS – generator tubes for generating frequencies over 300MHz

35 – the number of the serial number of the development of this type of tube;

B – a letter indicating the type of forced cooling: B – air.
