RoeTest (Röhrentest): Professional Valve Tester
The RoeTest has turned out to be one of the most essential tools in my workshop. It was designed by German engineer Helmut Weigl and built by yours truly. It’s a computer-driven valve tester with a highly sophisticated software which lets you know the condition of any kind of preamp or power tube due to its almost infinite measuring and testing possibilities. Add to that a program for tube matching and the possibility of printing tube characteristic curves. A must-have valve-testing tool!
