Brand New In Box JJ EL34 6CA7 Fully Tested Guaranteed Vacuum Tubes - Matched Pair

We only sell factory fresh tubes and NOT seconds as we are an authorized dealer for New Sensor (EHX) and JJ

The JJ Electronic brand is an industry favorite, a strong and trustworthy tube produced in the Slovak Republic. Their EL34 is outstanding, and is often chosen as an excellent upgrade from stock for any amp that uses EL34 tubes in the power section. They're also at a great price point for any working musician.

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.
