I have a 3-500z tube and just want to make a conversation piece out of it. I
am going to make a wood base for it and I would also like to feed some

wasn't sure how or which pins to do it with. Also I know it is a 5 volt tube
and 14.5 amp.do I really need that much to make it glow? Would 12 volt work?


12 volts will burn out the filament.

You might be able to try less than that. However, try an old computer
power supply, they should be able to give you either 3.3 volts at a
lot of amps, or 5 volts at a lot of amps.... I'd try the 3.3 volts
first, since you want a gentle glow, not the full filament.
