Vacuum Tube Night Light

Hello All,

I have four 12AX7A vacuum tubes out of an old guitar amp.  I'm not sure whether they work or not-the sound was extremely poor, but this could have been due to any number of things wrong with the amp, which is gone now.  I saved the tubes, as they still lit up when powered on.  I would like to turn the tubes into some kind of low glow night light/art project, but am not quite sure how to go about wiring them in parallel with one another, or even the correct voltage.  I have no experience with tubes, but would love to start learning, even just the basics...like how to power them up.  How complex a circuit would it take to do this?  Thanks!
