If you are not really experienced with tubes, a tube testers can be a good thing and a bad thing, sure you can weed out shorted tubes that aren’t any good, but you may also be throwing out tubes that are gassy and are not bad. My advice would be to get on the diy tube audio forum and do some research about tubes, tube life, and what are the pros and cons of tube testers.
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
