New Matched Quad Electro-Harmonix 6CA7EH EL34 6CA7 Big Bottle Vacuum Tubes FR SH. This product data sheet is originally written in English. New Electro-Harmonix 6CA7EH EL34 6CA7 Fat Big Bottle 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. Matched by Ip and Gm within 10%This classic big bottle 6CA7 is a tetrode rather than a pentode like the EL34. Both tubes are interchangeable but many prefer the rich and detailed sound of a tetrode to a pentode. Electro-Harmonix is rocking the vacuum tube community with the superior quality of the "EH" series tubes. Electro-Harmonix sound effects are world renown for the soulful warmth of their analog sound and their line of "EH" premium tubes continues in this tradition of classic tone. Matching power tubes for equal current draw is important for maximum performance.
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. The item "New Matched Quad Electro-Harmonix 6CA7EH EL34 6CA7 Big Bottle Vacuum Tubes FR SH" is in sale since Wednesday, January 23, 2019.
