General description

Double triode (tetrode) - 6H1P-EV is used to significantly amplify low-frequency signals and is used in previous stages of amplifiers, phase inverters, as well as in electronic scanning circuits of televisions (oscilloscopes, monitors). The body of the radio lamp is made in the form of a cylindrical glass bulb with nine rigid contacts, which allows you to operate the tetrode in any position. On an industrial scale, 6N1P-EV was produced until the 1990s by the Vostok production enterprise (Kaluga).

Basic technical characteristics

• Nominal and maximum voltage at each of the anodes: 250/300 V.
• Current in the anode circuit of each of the triodes: 7.5 mA.
• Current in the cathode circuit of each of the triodes: 25 mA.
• Shear voltage on the control grid: - 20 V.
• Input / output electrical capacitance of each triode: 3.1 / 2.2 pF.
• Nominal gain of each triode: 35.
