Very linear working 12AX7 / ECC83 with long anode plates and spiral heating, which makes the tube less sensitive to interference from AC heating.
We recommend this tube for audio and high-end amps as well as for "modern" Fender amps with more overdrive, but also as an input tube in old Marshall JCM800s.


Note: Tubes equipped with long plates are commonly associated with a "warmer" or "richer" sound, whereas those with shorter plates tend to deliver a "tighter sound". However, tubes featuring long plates exhibit increased sensitivity to vibrations and mechanical disturbances, rendering them less ideal for critical applications.

The Sovtek 12AX7WA is a defacto standard in 12AX7 tubes for many years yet because of its high dependability and its low noise floor.

This tube is selected for sensitive input stages (V1)

The Sovtek 12AX7WB has more gain and saturation than the Sovtek 12AX7WA. Its warmer, darker sound is preferred by Rivera, VHT, Demeter, and Kendrick, among other manufacturers.

The Sovtek 12AX7WC has a little bit more gain than the Sovtek 12AX7WB and  the 12AX7WA. The noise floor is still pretty low compared with other 12AX7 tubes and the dependabiliyt very high.
