This is the one and only 7868 on the market that will sound amazing and wont break the bank. These tubes will give your amplifier a whole new life. These babies will treat your ears and wallet right with their wonderful dynamics and rich, warm tone. 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. We guarantee our tubes for 90 days upon receipt. Noise and/or microphonic issues are covered.
