How does a vacuum tube work
WebFirst, a filament experiences a voltage drop along its length, as current overcomes the resistance of the filament material and dissipates heat energy. This meant that the voltage potential between different points along the length of the filament wire and other elements in the tube would not be constant. WebMar 20, 2024 · A tube is a small glass cylinder that contains a number of different components within a vacuum, and its purpose is to increase the amplitude of a signal. With a tube amp, a guitar’s signal is sent through tubes at a rate determined by controls on the device such as gain and volume.
