Brand New Electro-Harmonix 12AU7 ECC82 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. Built around the original GE 6189, this is a low microphonic and industrial grade 12AU7. This tube has a very clear and warm sound and was built to last.
This is a very linear tube which sounds great at any volume or in really any amplifier. A very versatile and affordable workhorse tube. The 12AU7 is interchangeable with a variety of tubes including the ECC82, 6189 and E82CC. This is the standard pin version.
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.
