The Tungsol 12AU7W / 6189 is a brand new pre-amp tube that is made in Russia. It is a premium quality 12AU7 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.
