I turned the lights off to look at the source of the corona arc and all I could see was a blue glow inside of the rectifier tube. I don't recollect rectifiers glowing blue inside. I was thinking that they are normally dark. But I don't spend a lot of time looking. Anyway, I was just looking through the slots in the bottom of the H.V. cage since I have the set on its side.

Hope I can get it to stop. It's not an actual arc or loud snap, but more like a hiss which is still an arc of some sort, just not the really bad kind.
