Description: Brand New Svetlana 6550 / 6550C 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 There is a lot of confusion when it comes to the legendary Svetlana 6550 tube and we want to clear it up. These are technically reissues though they are built in Russia using the same equipment as the originals. In the early 2000's New Sensor bought Svetlana and they are made in the Saratov plant now rather than the original Saint Petersburg plant. Other than where they were made, they are no different than the original 1990's SED or Winged =C= 6550 tubes. These are some of the finest new production 6550s money can buy. They're known for their robust quality and classic American 6550 tone. 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.
