Description: New Mullard Reissue CV4004 / 12AX7 Low Noise Vacuum Tubes - Matched Trio We only sell factory fresh tubes and NOT seconds as we are an authorized dealer for New Sensor (EHX) and JJ There are two versions of the reissue Mullard 12AX7. This version is better suited for guitar amplifiers. This tube was modeled after the British military CV4004. CV4004 is the military code for the 12AX7 and was designed to be more rugged. The short plate design cuts down on noise and microphonics which is especially important for this tube as these tend to have high gain. These are sweet sounding beauties that rival the originals. 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.
