The double triode with separate cathodes – 6Н1П allows you to increase the level of low-frequency signals to the required values and is used in pre-amplification stages, in phase inverters, as well as in the vertical/linear scanning circuits of televisions. The finger-shaped glass case with nine rigid contacts makes it possible to operate the radio tube in any position. There are two complete analogues of the double triode: domestic – 6Н8С; foreign – ECC-82.
• Input/through/output capacitance of each triode: 3.8 / 1.85 / 1.75 pF.
• Nominal gain of each triode: 35.
• Nominal operating voltage supplied to the anode: 250 V.
• Nominal operating voltage supplied to the filament: 6.3 V.
• Nominal current in the anode circuit: 8 mA.
• Nominal current in the filament circuit: 0.6 A.
