Brand New Electro-Harmonix 6922 Matched Octet (8 tubes). High frequency twin triode preamplifier tube used in studio and hi-fi equipment.This tube is built extremely well and will last for a long time. At Tonal Tubes we test and match preamp tubes using an instrument that allows us to test tubes for gain, transconductance, and noise, at real world voltages that would be seen in a guitar amp or hifi amp. We test every single tube that we receive to make sure it matches our standards. All tubes are also checked for shorts and leakage on a separate tube tester to ensure that all tubes will work flawlessly in your equipment.
For 6922 tubes we match with a maximum difference of 10% for gain. For each side of the tube. An example would be a 6922 tube that test 27.5/28.3 for gain.This tube would pass our tests. If a tube tests outside of our regulations then we simply do not sell those tubes.
Why You Should Do Business With Us. Every single tube is checked for shorts and leakage on a calibrated Eico 667 tube tester. Comes with original packaging straight from the factory, as shown in the picture. We are musicians who crave awesome tones.We all know that swapping out tubes can be one of the more effective ways of improving your tone. At Tonal Tubes, we help you achieve that next level tone.
