Brand New Electro-Harmonix EL84 6BQ5 Vacuum Tubes - Matched Octet. We only sell factory fresh tubes and NOT seconds as we are an authorized dealer for New Sensor (EHX) and JJ. Finally, an Electro-Harmonix version of the EL84 power tube. Expect them to take the heat in AC30 amps. Electro Harmonix says this about their tube, the EL84EH tube faithfully recreates the classic Mullard design.
Tri-lam plate material and selected screen wire increase thermal dissipation. The EL84-EH tube is a remarkable reproduction of a vintage tube that is capable of maintaining its sweet and musical tone under any voltage conditions. 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.
