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 12AX7EH provides high gain with ultra low noise and detailed, musical tone that rivals the most desirable NOS types.

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

The Sovtek EL84 series produces an unbeatable smooth, warm distortion sound. Excellent replacements in vintage VOX AC-30's and the like, very popular in Fender, Crate and Peavey amps.

• FAQ: If I order two or more of these tubes, are they all "the same"?
  Yes, the tubes are all "matched" and selected for the in the description mentioned amplifiers.
  FAQ: Can I replace the tubes myself or are adjustments needed?
  Adjustments are not possible on the listed amplifier (unless a bias potentiometer has been added afterwards). The replacement can therefore be done without adjustments.
