The Russian 6N2P (6Н2П) is a durable, low-noise, low-microphonic double triode, close in characteristics to the 12AX7 / ECC83. Manufactured by the VOSKHOD factory and carrying the ROCKET logo, it is a standard-production NOS (New Old Stock) tube, never used.

Min. order quantity is 50 pc. and more

Key Features & Specifications

Applications & Compatibility

• Primary use: voltage amplification in audio preamplifiers, tone controls, and driver stages.
• Audio use: a replacement for the 12AX7 / ECC83 in typical amplifier applications, provided the heater wiring is adapted.
• Equivalents: 12AX7, ECC83; the closest pin-compatible Chinese equivalent is the 6N4.
• Note: the 6N2P is the standard version; the -EV and -ER variants offer enhanced reliability and longer service life.

Condition

• Status: NOS (New Old Stock). Never used.
• Origin: Made in the USSR / Russia by the VOSKHOD factory.

Heater Wiring Note

6N2P tubes are a replacement for 12AX7 in any typical amp application, but they have 6.3 V heater voltage and would need a different wiring than stock 12AX7s.

Q: How do I rewire the socket to use such tubes?
A: 12AX7's filaments can be connected for either 12.6 V (pins 4 and 5) or 6.3 V (pin 9 and pins 4 and 5 connected together) operation. 6N2P's filament will take only 6.3 V (pins 4 and 5).

Why Choose This Tube?

The 6N2P delivers the familiar sonic character of the 12AX7 / ECC83 with the robust construction of Soviet-era production. Its low microphonic noise and stable performance make it a dependable choice for phono stages, line preamplifiers, and guitar amplifiers where quiet operation is essential. The Voskhod factory's ROCKET logo identifies genuine production, and the tube's 5,000-hour service life ensures long-term reliability. For restorers and DIY builders alike, this NOS tube offers a cost-effective path to authentic 12AX7-type performance, requiring only a simple heater rewiring to operate correctly in place of the original type.
