Equivalent: ECC83, 7025, 5751 Same tube as 12AX7LP except the LPS has a spiral fiment allowing it to handle AC without any hum or noise. For all vintage amps or for Hifi.
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.
Equivalent: ECC83, 7025 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).
