Product Description

UK Post free ( second class)

The JJ GZ34S  Rectifier  is used in famous amps such as the Vox AC 30  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.  NEW GZ34S’s do give a better sound!.

The USA equivalent part number for the Gz34S is the 5AR4

We also offer a 120 day from purchase warranty on the product ( excludes mechanical damage failure). we test your GZ34 on our analogue testers to ensure it is fully working before we ship to you. WE test every unit to give you the assurance of a good quality rectifier.

The JJ GZ34 Rectifier  is  the better alternative to replacing your old Gz34 with solid state rectifiers.  Old valve rectifiers eventually loose emission and the result is higher internal impedance. It can result in a lower voltage especially on the output stage. The result is the sound is less clean at higher volumes or can result in lower output watts from your amp. We recommend changing your rectifier every couple of years.  You can keep the old one as a spare for emergencies.

We test every GZ34S in house to assure you of receiving a quality product. We use AVO testers. Each GZ34S is individually tagged with the test results

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
