I accidently removed a tube from my preamp while the system was powered up and sent a surge through my Magnepan 3.7i speakers, a fairly loud pop. I'm worried that I might have damaged the tweeter ribbons, I know they have a reputation for being fragile. Is it possible that they can be damaged and still operate or would they shut down completely? Can part of a ribbon be damaged but not all of it? Can they distort? I'm not familair with ribbon technology so I need some advice. My paranoia thinks that there is a slight difference in the high end characteristics but I could just be imagining it. Any advice would be appreciated, thanks.
