The Tungsol 12AU7W / 6189 is a brand new pre-amp tube that is made in Russia. It is a premium quality 12AU7 vacuum tube built to match the performance of the military/industrial original GE 6189 tube. This tube performs well as a preamp tube or driver tube. The 12AU7 tube type is equivalent to the European ECC82 tube and can be used in any 12AU7 or ECC82 circuit.

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.

The best customer support!

It’s too soon to comment on the sound of these tubes in my Rogue RP1, except to say my initial impression is very good.

But I have to compliment the Tube Store’s customer service. One of the two tubes started hissing within 2 hours of installation. I called yesterday around 10am and described my problem. By 1pm today a free replacement (matched!) tube had made it from Ontario to Massachusetts. This is outstanding, unprecedented customer support! The Tube Store has made me a lifetime customer. I am very impressed!

Some cycling to achieve its potential

I have a PrimaLuna 300EVO pre amp using 6 12AU7 tubes. After running for an hour the overly bright highs diminished upon shutting down and restarting. The sound stage is very enhanced and bass has improved with more time of use. The high details are pronounced but not as bright as initially found. I feel like these are best listening to symphony and piano. They also rank as very good value.

Might be the best current production ECC82


The best current ECC82 production I've tried. Tested in the preamp output buffer and as an input lamp in the headphone amplifier. In both demonstrates a similar sound signature. The sound is quite balanced. heights are displayed clearly and strongly, but they are not harsh. The bass is very strong compared to many other ECC82 tubes. Mids have the right amount of detail, easily displaying complex textures. Overall a great modern sound. compared to the best NOS they may lack a little finesse in textures and a final touch

TungSols...total satisfaction!!


I replaced two preamp tubes in my PrimaLuna Dialogue Premium HP Integrated ( in the V11 and V12 positions) and noticed an immediate improvement in the quality of sound. Gone is the graininess of the proprietary tubes being replaced with a very quiet background and very detailed smoothness. Textures are now more prevalent along with a much bigger soundstage. The TungSols have a lovely 3D effect and are excellent at conveying separation. Subtle dynamics are much more obvious and "surprising" as they well should be. Pacing and rhythm are so much more delightfully apparent compared the PL tubes.
These Tung-Sols only have about three hours on them. I look forward tremendously to see how they open up in the next few weeks. This purchase is one of the best " bang for the buck" improvements I've ever done.
