Description
New Gain Matched Pair of Svetlana 12AX7 / ECC83 Vacuum Tubes
Svetlana vacuum tubes are among the best available at any price point, and are a great choice for anyone looking for high fidelity and reliability. Famous for a smooth balance of gain and low noise, the 12AX7 / ECC83 from Svetlana is a great choice when upgrading from stock tubes in both musical instrument and audiophile applications.
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.

Awesome Preamp Tube
I initially purchased the Svetlana 12AX7s for my phono preamp. They sounded great, nice balanced tone, very quiet and good gain. I rolled a couple of other 12AX7s in my phono preamp but always ended up with the Svetlana's back in my phono preamp. In the meantime, I was rolling a bunch of other 12AX7s in my integrated amp preamp V1/V5. Then it dawned on me to try out the Svetlana's in the V1/V5 of my integrated amp. BINGO! I hit the jackpot. The Svetlana's blew my system wide open. Huge soundstage, thunderous bass, and 3D that you can reach out a touch. The Svetlana 12AX7 is a better tube in tone and clarity than much more expensive preamp tubes in my collect. Wish I'd found this tube before I spent so much money on all the others. But that's the fun part of rolling tubes. You never know what combination of tubes will work well together. I can tell you that in my system (Black Ice Audio Fusion 3502S), the Svetlana 12AX7 is top-shelf!
