Product Description

The Tung Sol 5AR4 GZ34 Rectifier is the top of the line 5AR4 type rectifier that is made in the Saratov factory in Russia.  It is a re-issue of the original 5AR4 that was made in New Jersey.  It is used in famous amps such as the Vox AC 30  Valve rectifiers  and 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.  Replacing your old 5AR4/ Gz34 with a new Tung Sol 5AR4 GZ34 Rectifier does give a better sound!.

The UK  equivalent part number for the 5AR5  is the GX34. They are exactly the same specification.

We also offer a 120 day from purchase warranty on the product ( excludes mechanical damage failure). we test your Tung Sol 5AR4 GZ34 Rectifier on our analogue testers to ensure it is fully working before we ship to you.

The Tung Sol 5AR4 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 Tung Sol 5AR4 GZ34 Rectifier in house to assure you of receiving a quality product and the test results are makred on the valve box

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

"I ordered the quad for my stereo amplifier and they sound really great (more tight bass, well focused mids, sweet and “airy” highs. A step-up from the previous set. They were sent very well packaged and were shipped promptly. I cannot coment on the matching process, since I am not that experienced, but common sense says it is an advantage. Fact is that they sound really good. Totally satisfied and I guess I will be a regular customer from now on.."- A.L. 29th October, 2019
