Description

The G-811 (Г-811) triode is used as an oscillator in RF equipment.

The G-811 high-frequency triodes are resistant to ambient temperature from -60 to +70°C and relative humidity of 95 to 98% at +25°C, as well as to mechanical loads: vibration loads up to 2.5g and multiple impact loads up to 12g.

All tubes new, military equipment and have "OTK" mark. Near equivalent: ---. The tube is manufactured by the Ryazan Plant, Russia.
