The 6N2P, (Russian: 6Н2П) also sometimes spelled in English "6H2Pi" is a miniature 9-pin dual triode vacuum tube manufactured in USSR, Russia and China with characteristics similar to the RCA 12AX7. The most significant difference between the two is that 6N2P has its two filament elements connected in parallel, unlike the series filament connection of the 12AX7, and it is thus only possible to operate it from a 6.3 volt, 300 mA filament supply (whereas a 12AX7 may be operated from either 6.3 or 12.6 volts.) The 6N2P also has slightly lower gain than a 12AX7.
Different 6N2P versions
In the 1970s an improved and more rugged version of the 6N2P was introduced, designated 6N2P-EV (Russian: 6Н2П-ЕВ) Currently, a 12AX7 variant derived from the 6N2P-EV is being produced by Sovtek, under the designation 12AX7WA.
