    I have a v1 tube that is glowing only at the top. The base, or bottom, does not glow at all. I get no sound and the cables and speaker work perfectly as I have tested elsewhere.

    This seems like a very odd occurance and one I have never seen or experienced. Would this simply be a bad tube, or something that I should seek out professional assistance?

    Thanks for the help!

    A glowing tubes means nothing other than the heaters are working. Just put a new tube in there and see if that works. A good rule of thumb is to always have spare tubes on hand.
