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.

Superb

I've tried GT's, JJ's, and Sovtek's in my Peavey Classic 50. The Tung-Sol tubes sound great! Very musical. I installed some in my AXL amp as well. I never had any go microphonic yet, but I think it doesn't fare well as a PI stage. In my C50 it was okay there, but in my AXL Akita it failed after two years of very light use. It's still going in my C50 after 4 years.

Great tube!

I replaced the tubes in my little Bugera V5 after reading the reviews on this site. With only a single 12ax7 and a single EL84 I must say that a direct A/B test with a friends stock V5 proved the Tung Sol 12ax7 tubes win! Much warmer and pleasing tone, not as bright, it made the little amp sound bigger and I use it to push 2x4x12 cabs when I don't want to risk getting the cops called on me!

overrated tube

by

I've got many of these tubes and have compared them to many other new tube offerings and have come to the conclusion these are vastly overrated. I purchased these based on the reviews and description, and when comparing to sometimes awful stock or worn tubes I can see how they would be an improvement but there are better offerings for tone and clarity. I've had them in for different guitar amps all with different types of power tubes and the basic sound is raw and crunchy, with high gain, but also flat. I don't mean neutral I mean flat. The low end was also muddy even at lower gain and volumes. I found that the lower priced Svetlana 12AX7 to be more articulate, sweeter sounding cleans and some of the best sounding crunch available, yet still warm. Good option in this price bracket. If you want a tube that's far superior look to the Preferred Series 7025, any of the Gold Lion ECC83, or Northern Electric 12AX7. The tung sols make better Christmas ornaments than guitar tubes.

Great preamp AND power tubes!!

by

I've been using Tung-Sol preamp and power tubes for the past 3 years. They sound amazing! Low noise; rich and full of harmonics. I like em in my JCM 800 (Slash) #34 replica for the clear highs and moderate gain that they produce.  These tubes are great for moderate gain output,low noise and clear highs - I HIGHLY recommendthese tubes.I use the 6550 power tubes which are great sounding tubes as well.Not only are these great tubes, but they're very reasonably priced.Try 'em - you won't be sorry - I promise!!!

High Gain,Big Bass,somewhat scooped mids. They will open the amp's sound in the same way as a presence knob will. Highs can be over the top,so be careful. Very low noise for a high gain tube.
