Sigh.....

Tubes Asylum

Questions about tubes and gear that glows. FAQ

One of my Penta Labs kt88's has a crack in the glass. I've just noticed it and powered down the amp. The tube is still hot but it feels like a ridge protruding out of the tube. I've never seen this in any of my other tubes before. I am going to pull the other 7 and inspect them as well. I've included a couple of photos of this abnormality. Please look at them and let me know what you think. Thanks
