Description

New Gain Matched Pair of Tung-Sol 12AX7 / ECC83 Reissue Vacuum Tubes

The Tung-Sol 12AX7 is one of the very best new production 12AX7 models offered. These tubes are high gain, low microphonics and are VERY warm and detailed. You'll get true 3D sound with these. The filaments are almost completely encased within the plates so they don't light up much, but they are fantastically quiet. The tone is comparable to the best vintage 12AX7s like Mullard or Telefunken.

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.

    Tung-sol 12ax7

    Posted by Kevin woodbury on 28th Oct 2023

    I am using a pair of these tungsol 12AX7 tubes and a black ice audio FX 10 integrated amplifier. I have tried about three different types of 12 X sevens with this piece, including some NOS Matsushita 12AX7’s. These are far the best I have had in my system. They are open detailed, but smooth and extremely cohesive top to bottom just a beautiful sounding tube. If you have a black ice audio piece, you have to try this tube in your gear.

    Great tube for my ART MPA II

    Thanks to VivaTubes for explaining the tube characteristics. They helped me to make my decision without telling me what tube brand to purchase. The transaction was seamless and the delivery fast. I will be using them again.
