Tung Sol 12AX7 Made in Russia
build for high performance and long life
Tungsol 12AX7 is the Ultimate 12AX7. Big, warm, and musical. High Gain, ultra-low microphonics, and superb linearity with a dynamic 3-D sound.
One other note about the construction of these tubes is they have filaments that are almost completely encased in the plate structure. They don’t “light up” brightly when working properly.
Note to audiophiles: These tubes are great for linestage preamps, but generally not phono stages where a very low noise floor is required.
