One of my YO186 have developed a dark eye on it’s getter. Even the tube still measures fine and sound fine but I wonder what make some of those tubes to get dart spat of the getter gloss. I have seen it before and do not have any association between the presence of the dark eyes and the tube quality, still I would like to know where this anomaly come from and if is it a sign of anything.
