Q: Someone told me that if I don’t warm up my tube gear before I use it, the vacuum tubes will be destroyed by cathode stripping. Is that true?
A: See Word for the Day “Cathode Stripping” for a definition of the term.
Experts disagree whether cathode stripping is a real phenomenon or not. But whether cathode stripping is a “real” danger or not, for best performance, best stability, consistent tone, and longest tube life, it is wise to allow a tube-equipped piece of gear to warm up thoroughly before you begin using it.
