The 6N1P (Russian: 6Н1П) is a Russian-made miniature 9-pin medium gain d
ouble triode vacuum tube intended for use as a line audio amplifier and cathode driver.
Basic data: Uf = 6.3V, If = 600 mA uM = 35 Ia = 7.5 mA S = 4.35 mA/V Pa = 2.2 W
The 6N1P has similar ratings to the 6DJ8 and in the past was sometimes rebranded as such, however, because of the differences between the two types (such as twice as high filament current of an 6N1P and three times smaller S value) it's not suitable as a direct replacement in 6DJ8 applications and vice versa.
A ruggedized/extended ratings version of the tube is designated 6N1P-EV (Russian: 6Н1П-ЕВ)
It has currently found a use as a driver tube in hi-fi tube amplifiers (such as Audio Research models VS55 and VS110) because of its excellent low distortion and low noise characteristics. The tube is being manufactured by "Voshod" plant in Kaluga, Russia (see [1]) and is being distributed in the West under the Sovtek and Svetlana brand names.
