6N3P-I

6N3P-I double triode with separate indirectly heated cathodes in finger-glass design. Designed to amplify voltage and generate high frequency oscillations.
The 6N3P-I double triode is used as a high-frequency grounded-grid amplifier, as well as a mixer or local oscillator in radio engineering devices operating in the ultrashort wave range. Can be used in low power VHF receivers, pulse circuits and low frequency pre-amplification stages.
Works in any position.

I – a tube designed to operate in a pulsed mode.
