Question about Vacuums
Hi. It all depends on what you are constructing, and the type of vacuum tube you have.Most tubes are used as amplifiers so if you were making an audio amp an input device like a microphone will be needed, a power source to drive the tube (sometimes a very high voltage! ) and an output device like a loudspeaker.
I'd suggest checking out some basic electronics tuition websites to find out what else you might need, and maybe experiment with small transistor circuits first - they are a lot safer.
