The 5U4GB Electro Harmonix Rectifier appears in many famous amps from Mesa Boogie, Fender and more.
Valve rectifiers introduce a characteristic “sag” to amplifiers, which is a bit like compression. The result is a better sustaining note at the same volume as an amp with solid state rectification. The 5U4GBs give a better sound!
The 5U4GB produces 100 watts of HT voltage, so is excellent for 50-80 watt guitar amps. The original black & silver-face Fender Deluxe Reverb amps used the 5U4 rectifier.
We test every 5u4GB in-house before shipping. We include the test results on the box to assure quality.
Includes a 180 day warranty.
The EH 5U4GB is a better alternative to replacing an aging 5U4 with a solid state rectifier. Over time, valve rectifiers lose emission and so their impedance increases. This leads to lower voltage, reducing clean headroom and lowering maximum volume.

We stock a whole range of rectifiers from EHX, JJ, and Sovtek for all amps, tested in-house for maximum quality.
Note: Valves use high voltages and these voltages are dangerous. The amp can retain these high voltages even after being switched off. If you are not sure of fitting them, please seek the services of qualified personnel.
