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.

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.

Electro-Harmonix has released a low noise, low microphonic version of the 12AX7 that meets all specifications required for the tube to be designated 7025. The original 7025 tube was a 12AX7 that was tested and selected for the lowest noise and microphonics for use in the critical first preamp stages of amplifiers where noise and microphonics could be an issue. In order to ensure that the 7025 specification is consistently met, Electro-Harmonix has redesigned the structure of the 12AX7 and has implemented construction techniques to ensure the absolute lowest noise and microphonics possible. In all samples tested, noise and microphonics could not be detected.

The Electro-Harmonix 7025EH has a mid-range that gives clarity and definition to the sound and a smooth top end for warmth and balance. With these characteristics, along with the exceptionally low noise and low microphonics, the Electro-Harmonix 7025EH will work equally well in vintage and modern high-gain guitar amplifiers, as well as sensitive phono preamps.
