New In Box 4 JJ Electronics Tesla 12AX7 ECC83-S Vacuum Tubes - Matched Quad We only sell factory fresh tubes and NOT seconds as we are an authorized dealer for New Sensor (EHX) and JJ The JJ ECC83-S / 12AX7 is possibly the most popular 12AX7 ever made. There is a reason major brands like Fender and Marshall come with these stock, they're a bargain and excellent quality. Suitable for audio or guitar. ECC83 is the European designation for this tube, ECC83 and 12AX7 are identical tubes. These look different than typical 12AX7s and the reason is because they were redesigned several times by JJ until they got them perfect. These are especially low noise with their unique plate design with plenty of gain. 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.
