Description
New Gain Matched Septet of Sovtek 12AX7WA / 7025 Vacuum Tubes
Vacuum tubes from Sovtek have long been considered top-shelf, and for good reason. They are tonally rich, robustly engineered, and well-suited for the demanding audiophile or musician. The Sovtek 12AX7WA / 7025 / ECC83 is noted for balancing low-frequency warmth and crisp high end, and is always a smart choice when upgrading.
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.
