World best seller !
Our 12AX7WA is world-renowned for its smooth, round tone. This ultra "low microphonic" tube is used by Fender®, Ampeg, Carvin, and Hartke, among others.

The Sovtek 12AX7WB has more gain and saturation than our WA. Its warmer, darker sound is preferred by Rivera, VHT, Demeter, and Kendrick, among other manufacturers.
Low gain 12AX7
The 5751 can be used instead of a 12AX7. It features 30 % less gain, perfect for clean sound of Hifi applications. Very low noise, no microphonics and a crystal sound. Very appreciated in studios (compressors and preamps).
