New Old-Stock (N.O.S.) tube.

The 12AX7-A is a miniature high-mu twin triode each section of which has an individual cathode connection. The 12AX7-A is especially suited for use in resistance-coupled voltage amplifiers, phase inverters, multivibrators, and numerous industrial-control circuits where high voltage gain is desired. A center-tapped heater permits operation of the tube from either a 6.3 volt or a 12.6 volt heater supply. Use of the 12AX7-A is advantageous in applications that require low hum and microphonic output.

Did a eunuch carry them on a pillow and place them with silken glove in a unicorn's butt to test for mirophonics? No, but they test as new, the ones I got had boxes and tubes in beautiful if not immaculate condition, and sell for 1/2 of what the "snake oil" website sell the same, OEM, and ones out of box with faded paint that test new for.
My amps have never sounded like this, I can never go back. NOS are worth it.
Take a chance and order, or call a salesperson to see what they have.
My tone and playing will never regret getting these.
