The signal is the part we really all care about when it comes to music. How long they take to warm up depends on the tube itself. This is why you want to let your tubes warm up a bit before actual use.

The heater is what gives the free electrons the energy to be released from the cathode and flow then to the plate. The Heating element is constant voltage which is specific to the tube being used in the circuit. This voltage will control the speed at which electrons move from the cathode to the plate, when positive, they move faster, and negative grid voltage has the opposite effect. The grid voltage is variable from negative to positive. The Signal that is being amplified and the grid voltage when applicable. There are a couple of current paths in the tube, you have the heating element’s current. The path of electricity through the tube will help you understand what it is doing to the current. Not all tubes are constructed exactly the same however most tubes in audio applications will be similar. Below is a diagram outlining the parts of a common vacuum tube.

However vacuum tubes are a little more complex than that. In basic terms they are glass tube with a cathode and anode that pass electrons from one side to the other. There triodes, tetrode, pentodes, and so on. The name diode comes from di meaning 2 and that is has only 2 electrodes inside. You have likely heard of modern diodes which are used in circuits to control the direction electricity flows.

There are many types of tubes and the simplest is a diode. In almost all cases they are used to amplify a signal, or at least in audio equipment. You may know what they are and what they do, but how do vacuum tubes work, and what do they actually do. Vacuum tubes have been a staple in audio for nearly a century.
