"95/91 or 46/41" If these numbers are written on the side of a tube with a Sharpie they are the test results of a 2 section tube. Unfortunately they are meaningless unless the tube tester is known along with the results chart. Now generally 95/91 is generally a good reading, however 46/41 is not. Take this with a grain of salt as the tube tester is unknown. Always buy tubes, especially ones that need matching from a reputable vender. A Google search will give you a start.
Tube tester?
Hello! I have tube amplifiers, and I have ordered tubes for my amplifiers, but I don’t know how to read their quality, available, power, longevity, and how they are rated. Does anyone know which tube tester will work for CARY tube amps? Do I need to spend a lot of money? How do you read tubes that are marked :(I.e) 95/91 or 46/41
