    Description

    Brand New Electro-Harmonix 300B Gold Pins Ceramic 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
    Ultra-long life, high-quality construction and superior sonics with improved performance make it a top choice over 300B types made by other manufacturers. Like the original Western Electric 300B, it has the eight course, directly heated filament, 40 Watt plate dissipation, classic large-shoulder tube glass, and is available singly or in matched pairs. The 300B EH's plate curves and static DC characteristics (plate resistance, transconductance, mu) also exactly match the originals for superior performance in any vintage or modern 300B amplifier.
    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".
