7025 - Electro-Harmonix

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 selected for the lowest noise for use in the critical first preamp stages of amplifiers. Electro-Harmonix has redesigned the structure of this tube to ensure the absolute lowest noise and microphonics possible from a 12AX7 family tube. 

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.
