Triode Preamp Tube for Guitar Amplifiers
Whether you're looking for a single tube or a matched set, we suggests you trust your tone to tubes you can rely on. Bugera valves are subjected to rigorous testing to ensure you'll get great tone right out of the box. First, this 12AU7 preamp tube must pass a 48-hour burn-in where it's pushed to the limit. Next, a vibration table test ensures the structural integrity of each 12AU7 will stand up to your gig schedule. After its been warmed up and shaken around, each tube goes through computer-controlled testing to evaluate 12 more operating parameters, so you know when your new Bugera 12AU7 preamp tube arrives, it'll be in perfect operating condition.
