Description

New Plate Current Tested Electro-Harmonix 6973 Vacuum Tube

Thanks to Electro-Harmonix the 6973 is finally affordable and easy to find! This tube has long caused trouble as the originals are so scarce. Many companies were re-branding the less powerful 6CZ5 tubes and selling them as 6973. The two are related; however a 6CZ5 would break up far too early and would burn out prematurely as they cannot handle the voltage of a true 6973. This is a rich and warm sounding tube with great dynamics just like the original. You can run these in any circuit that calls for 6973 or 6CZ5 but you cannot run a 6CZ5 in place of a 6973.

Will work in place of: 6973, 6CZ5

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.
