"Tube" refers to the tubular shape of the device, whereas "valve" refers to the function of a simple diode tube. Up to the mid-1930s, the German military used civil vacuum tubes for their mobile amplifiers, receivers and transmitters. Those tubes had actually been developed for civil ...
An electron tube has two or more electrodes separated either by vacuum (in a vacuum tube) or by ionized gas at low pressure (in a gas tube). Its operation depends on the generation and transfer of electrons through the tube from one electrode to another. The source of electrons is the ...
