EH7025 Preamp Valve Balanced
EH7925 Preamp Valve . This valve was re-introduced in 2020.
This version is specially selected to have the two triodes closely matched . This ensures even wear and better tone in amps with push pull output stages. In other words amps with two or more output valves
Electro-Harmonix has released a low noise, low microphonic version of the 12AX7 that meets all specifications required for the valve to be designated as a 7025. The original 7025 valve 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 EH7025 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 EH7025 will work equally well in vintage and modern high-gain guitar amplifiers, as well as sensitive phono preamps.
