Product Description

JJ 5U4GB Rectifier Valve

The JJ 5U4GB Rectifier Valve is used in famous amps such as the Fender amps. Valve rectifiers  are characterised by the ” sag” that they introduce which is a bit like compression. The result is a better sustaining note at the same volume as an amp with solid state power supply rectification.  JJ 5U4’s do give a better sound!. Each unit is tested on an Avo tester and the results are on the boxes and on each valve.

The 5U4GB will produce a 100 watts of HT power so is excellent choice for 50-80 watt guitar amps.  The original black & silver-face Fender Deluxe Reverbs used the 5U4G rectifier.

We also offer a 180 day from purchase warranty on the product ( excludes user caused mechanical damage failure). We test every 5u4GB on our analogue testers before shipping. We test every unit before shipment to give you the assurance of a quality brand new product

The JJ 5U4GB Rectifier  is the better alternative to replacing your old worn 5U4’s  with solid state rectifiers.  Over time, valve rectifiers loose emission and so their impedance increases.  This leads to a lower voltage especially on your output stage in your amp which can mean less clean sounds at higher volume or even lower maximum volume.

We test every 5U4GB that we ship.

 There is an international shipping options for UK and international customers.  Just make your selection at checkout. Get your valves delivered faster!

Note: Valves use high voltages and these voltages are dangerous. The amp can still retain these high voltages for some time even after being switched off.  If you are not sure of fitting them , please seek the services of qualified personnel
