Description

New Gain Matched Trio of JJ Electronic (Tesla) 12AX7 / ECC83S Vacuum Tubes

The JJ 12AX7 / ECC83S tubes are one of the most popular new production 12AX7s ever made. There is a reason major brands such as Fender and Marshall come with them as stock tubes. At a lower price point, they are excellent quality tubes for audio and especially guitar. JJ’s 12AX7 looks different than their counterparts, due to JJ redesigning them until they got them just right. Due to this, their new plate construction makes them especially low noise on top of plenty of gain.

Will work in place of: 12AX7, ECC83, 12AX7A, 7025, 12AX7WA, 12AX7WC, 12AX7WB, ECC803S, CV4004, CV492

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.
