6N3P by pc10201


From Wikipedia, the free encyclopedia

The 6N3P (Russian: 6Н3П) is a Russian-made direct equivalent of the 2C51 medium gain dual
triode vacuum tube. It may be used as an amplifier, mixer, oscillator or multivibrator over a
frequency range AF through VHF. The Russian tube is slightly larger in size than the American

Basic data
(per each triode)
Uf = 6.3 V, If = 350 mA, µ = 36, Ia = 7.7 mA, S = 4.9 mA/V, Pa = 1.5 W

History of use
6N3P was widely used for FM band radio input unit stages (nearly all 1960s Soviet radios with FM band employed the same
input unit on a separate subchassis). Currently it has found use in DIY preamps. A ruggedized/industrial version of the tube is
designated 6N3P-EV (Russian: 6Н3П-ЕВ)

Chinese 6N3
eBay has proliferated with pre-amps apparently from Hong Kong that are largely populated with the 6N3, which is said to
be the Chinese version of the 6N3P. The 6N3Ps are newly made (unlike the Soviet "new old stock," and the pre-amps
appear to be the product of a cottage hifi industry.
