7025 EH Balanced preamp valve by Electro Harmonix

The 7025 preamp valve became very popular in the 1960s with many leading amplifier manufacturers specifying them, particularly Fender.

Our replacement Balanced preamplifier 7025 EH valve is the perfect high quality replacement for any amp that uses a balanced ECC83 (12AX) preamp valve in the phase inverter position. Whereas other preamp position do not need to be balanced it is generally considered that the phase inverter position should have a balanced valve if possible. This means that both sides of the valve are equally matched so that all the power valves receive the exact same power.

Electro-Harmonix has completely redesigned the structure of the 7025 compared with the standard ECC83/12AX7.

This has resulted in a preamp valve with the lowest noise and microphonics possible. In all samples tested, noise and microphonics could not be detected. As a result it can make a huge difference when useD in the V1 position, although all ECC83 positions in your amp will benefit from the upgrade.

The Electro-Harmonix 7025EH has a beautiful mid-range that ensures clarity and definition as well as an exceptionally smooth top end for warmth.

This valve will work equally well in modern high-gain guitar amplifiers, as well as the extremely sensitive phono preamps.

About the EH 7025 balanced valve.

So, the 7025 valve is a low hum and low noise version of the ECC83, but will you hear the difference?

99% of valve amplifier manufacturers use the standard ECC83 (12AX7) but purists and professionals love to use the 7025 instead. On many amplifiers, particularly Fender, the 7025 is the specified valve to ensure best performance.

We have tried this valve in a large number of amplifiers, both new and old, and found a significant improvement in all cases.

You can order 7025 preamp valves singly or in multiples as they do not need to be ‘matched’ like power valves. We always recommend that you change all your valves at the same time (pre-amp and power valves). It’s a small price to pay to keep your amp sounding better than ever.
