Without pictures to show what you are talking about, it is nearly impossible to answer this last. What rube is it for? Is it a locktal or an octal tube? Your radio uses both types. The 35Z5 and 50L6 are OCTAL tubes. The others are LOCTAL tubes. The bases are DIFFERENT ! Make sure you got the right kind of socket for the tube. You must become more observant of these things.
