A premium, high grade Russian preamp tube in generic box


These are unused old stock with generic tube boxes. The Mesa Boogie MESA 12AX7 Russian 2 is a premium-grade preamplifier tube. It’s designed to provide high gain output with an overall balanced tonal quality. You’ll also find that the MESA 12AX7 is both consistent and reliable in its smooth, balanced tonal response. The MESA 12AX7 is a lively, open, and expressive tube. Great in any brand of amplifier, not just Mesa Boogie.

    Same great Mesa tubes in a plain box. Got another order coming before I even plugged these into my amp. Sweet tubes at a kind price.

    Premium Mesa Preamp tubes sound warm and great clean tones as well as hi gain overdriven ones. Picked up a few more for my Peavey Bravo. Love those tubes.

    Have picked up a few of these tubes to see what tube will arrive. Ones Marked Russian 1, another Russian 2 and a couple others so far. Fun times tube rolling and see what sounds best where and with what combinations. All tested screened quality valves. Thank you.

    Been rolling tubes and trying the preamp tubes in the V1,V2, and phase inverter positions in my amps. Great quality tubes with warm sounds and low noise and microphonic vibrations.

    All of the Mesa tubes I have tried have been high quality with low microphonics. Best rebranded tubes I have tried.
