New Tested Tung-Sol Reissue 6SN7GTB Vacuum Tube 6SN7 6SN7GT – Single We only sell factory fresh tubes and NOT seconds as we are an authorized dealer for New Sensor (EHX) and JJ The 6SN7GTB is the low noise version of the 6SN7, 6SN7GTA, and 6SN7GT. They are all compatible. This is one of the only New Production 6SN7’s available and given how musical and warm it sounds, I’m not sure we need any others as long as they keep making this one! 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.
