Description

New Matched Pair of JJ GZ34 / 5AR4 Rectifier Vacuum Tubes

JJ is an undisputed leader in modern vacuum tube manufacturing, and for good reason. Among rectifier tubes, their 5AR4 (GZ34) is an industry favorite, as it provides consistent performance along with great build quality at a reasonable price point.

Will work in place of: 5AR4, GZ34, U77

Testing and/or Matching

At VIVA TUBES, all of our customers get the same high standard of testing and matching. Some sellers charge more for premium matches but we believe all of our customers should get the same level of quality and service. 

Tubes are tested and/or matched at full operating voltage with regulated power supply on a Maxi Matcher tester for general mutual transconductance (Gm). In addition, power tubes are tested/matched by plate current (Ip) and preamp tubes are tested/matched by gain. Rectifier tubes will be tested for emissions on a calibrated military grade tube tester. 

Our goal is to match within 5% with an upper limit of 15% (15% is the industry limit to consider a set).

Hand written test data included.

Note that we do offer a few models which are tested & matched at the factory. They will be matched by the same parameters (Ip & Gm) but to the manufacturer's standards. Factory testing will be indicated in the item title and description. 

Guarantee

We offer a minimum 90 day guarantee covering functional defects - including noise unless otherwise stated. The guarantee period begins the day you receive your order.

    Best sounding rectifier tubes

    Posted by John T on 12th Nov 2023

    I put these JJ tubes in my PrimaLuna EVO-300 Preamp, and I'm now hearing it at Its best. I would never go back to the stock rectifiers or any other.
