Description
New Gain Matched Octet 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, CV492Testing 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.
