Triode

A triode is an electronic amplification device having three active electrodes. The term most commonly applies to a vacuum tube with three elements: the filament or cathode, the grid, and the plate or anode. The triode vacuum tube was the first electronic amplification device...

Basic Data

(per each triode)

Uf = 6.3V, If = 350 mA uM = 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.
