    Brand New Electro-Harmonix KT90 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
    The greatest KT90 of all time. Electro-Harmonix really hit the nail on the head with this one. This tube has a bit more power than a KT88 but with the classic warm and bass drenched sound of an EL34. The tube really is the best of both worlds. These are drop in substitutes for an 6550 or KT88 amplifier – just make sure to adjust your bias.
    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.

Noise and/or microphonic issues are covered. We reserve the right to deny returns for buyer's remorse including the buyer's opinion on "tone".
