The Tung-Sol name and trademark have been acquired by the New Sensor Corporation. This new production Tungsol tube is manufactured at their Xpo-Pul factory (also known as Reflektor) in Saratov, Russia. New Sensor is an American corporation and since taking ownership of this factory has been steadily improving the quality of current production tubes.

From our review of this tube: "There are only so many ways to describe tube tone and most have become cliches. The Tung Sol 12AX7 has the gain and drive of a Chinese 12AX7 and the pure tone of a Mullard or Brimar."

According to the manufacturer, this 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.

Warmth and Emotion


This is my choice in 12AX7 tubes for the pre’ section drivers of my twin stereo power amps… I’ve tried a few including the Tung-Sol Gold (see my review of the Golds) but these tubes continue to delight me. They have very nice extended and articulate bass (maybe too much for some listeners) with beautiful lower midrange and an upper midrange and treble that I find very good. The soundstage is nice and open with height, width and depth. In my system these tubes present a warmth and an emotion that completely engage me and that I can listen to tirelessly. I highly recommend them.



Having Sovtek 12ax7WA, 12AX7WXT, 12AX7LPS, and Chinese Golden Dragon (Shuguang) to test this tube have the more hard and metallic sound. Probably not suit with my hifi amp (audio innovation s-500)

Nice tubes

Retubed my Hiwatt DR504. Had the EH glass an amp tech installed when I had it recapped about ten years ago. One of them was acting up so I replaced all four along with both EL34’s. I was stunned. Beautiful sound. Never stepped on a pedal. Just played that old Britt amp clean. Very nice tubes

Bluesbreaker RI use


I just retubed my mid-90's Marshall Bluesbreaker RI and replaced the EH 12AX7's that I previously used with these new Tung-Sols. Great sounding tubes. Smooth but with the right amount of bite when the amp is cranked. I liked the EH's but the Tung-Sols are an improvement. I think they may be as good as the NOS JAN's I had in the amp years ago - but that was long enough ago that my memory can't be completely trusted.

Well worth trying these Tung-sol tubes.


installed these in my old 70's Garnet amp and they brought it back to life. Really tamed the highs and mids with more clearer bottom-end crunch when digging in. Have them paired with 2 Mullard EL84's and a 12" Celestion Vintage 30 speaker....great setup.
