6N3P-EV (original box)

Description

Russian tube 6N3P-EV double triode with separate indirectly heated cathodes in finger-glass design. Designed to amplify voltage and generate high frequency oscillations.
The 6N3P-E 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.

E – the letter characterizing the increased durability of the tube
V – a tube with increased reliability and mechanical strength.

Near equivalent to tubes: ECC42, 2C51, 5670, 6385.
