    It's a little bit of gas in the tubes. Not a real big deal. Lots of 6L6's glow like that when you look in the back of a Fender Amp. Lew

    I've heard they glow blue when they run too cold. Anyway, that's what I've read in a Mike Soldano interview.

    i was told it's common in 6l6 tubes.


    smelling burned, where did you store them? if there was any dust on it, then you smelled that

    My EL34's have always had little bits of blue in them. Makes them look pretty.

    As long as they're not completely blue (or red), I think you're all set.

    It means your tubes are sad. Play "Shiny Happy People" by REM through them and they'll cheer right up.

    lol


    If there's just little blue thingys flying around, it's ok... if it's really glowing blue... that might be a prob AFAIK... I had an article about that once... but others should have more experience with that anyway...

    They work fine now anyway. Thanks guys!
