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 2A3 is noted for its timeless profile and overall warmth, and is always a smart choice when upgrading..
Testing and/or Matching
We test and/or match our tubes by Gm & Plate Current using a state of the art digital Maxi-Matcher tube tester. The Maxi-Matcher simulates a real circuit and tests tubes in real-world conditions. We also check our tubes for other issues like shorts on calibrated and vintage tube testers. We match our tubes +/- 5% with an overall tolerance of 10%.
While we do screen for noise and microphonics, even the best tube testers are quite bad at finding these faults. The only real test is with your ears. We guarantee that our tubes will be free of noise or microphonics but please be aware that there isn't a whole lot we can do to ensure your tube won't be. To combat this issue, we are quite liberal in accepting returns for these reasons.
