Orange Valve Tester MKII | Review - Guitar Interactive Magazine

The Orange Valve Tester MKII is a game-changer for tube maintenance, offering intuitive diagnostics that provide clarity on your valves' performance. Its compatibility with a wide array of tube types and its ability to deliver "Good," "Worn," or "Fail" assessments makes it invaluable for both guitarists and techs. While the device's testing process can be somewhat slow, the detailed feedback is particularly beneficial for professionals. However, at a hefty price tag of $1,075, it may not be a feasible investment for casual users. If you're serious about your valve amp setup, though, this tester could prove essential.
