Brand New Tung-Sol Reissue 7591A Plate Vacuum Tubes - Matched QuadWe only sell factory fresh tubes and NOT seconds as we are an authorized dealer for New Sensor (EHX) and JJ
Built around the same specs as the original Tung-Sol 7591A, this is the perfect choice for those looking to replace tubes in their Scott or Harman Kardon amplifiers or any amp that calls for 7591A. Because of their availability matching by plate current is a breeze unlike in the vintage world. It is nearly impossible to find a truly matched vintage set due to lack of availability.
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.
