The beam tetrode - 6P1P-EV serves to increase the power of low-frequency signals, which allows its use in the output stages of amplifiers and receivers, as well as in generators and multipliers. The radio lamp is made in the form of a glass cylindrical bulb and can be operated in any position. Until 1985, the tetrode was produced in St. Petersburg.
