6N2 6N2P B9A NOS fits Little Bear valve amplifier preamp T10 T11

The Russian 6N2P offered here is NOS (New Old Stock) and makes a superb upgrade replacement for the 6N2 tubes supplied with many Chinese preamplifiers such as the Little Bear T10 or T11 RIAA preamp (3 valves required). Near equivalent to E88CC or 6922 valves but higher Mu or gain than the E88CC or the similar 6N1P. This valve may be used for preamp and driver stages of hi-fi or guitar amplifiers (where the 9 pin B9A pinout is the same as 12AT7 / 12AX7 except that the heater is wired differently to pins 4 and 5 only and runs at 6.3V only and not 12V).

Current stock was made at the "Voskhod" Kaluga Radio Tube Plant near Moscow, Russia, in the 1970's to 1990's, but sourced / purchased from the Ukraine.

A great value high quality double triode with shielded sections also suitable for use in any high end stereo designed around these particular valves or a superb budget alternative to ECC83 or ECC82 for home build amps where you can wire the heater slightly differently to suit these valves.
