It's one of the main reasons that testing tubes is a 50/50 deal. All it tells you is whether it conducts or not and if so is it enough or a little. When a tube is in the radio and warms up it could short, stop conducting, talk to It's neighbor, glow, squirm and some other things that will make your head spin. Even when you have spares there's still a good chance of goofy symptoms. LOVE it!
