2vacuum tube — 1. Also called, esp. Brit., vacuum valve. an electron tube from which almost all air or gas has been evacuated: formerly used extensively in radio and electronics. 2. a sealed glass tube with electrodes and a partial vacuum or a highly rarefied… …
3Tube sound — (or valve sound) is the characteristic sound associated with a vacuum tube based audio amplifiers. Some audiophiles prefer the sound that is produced by the distortion characteristics of tube based amplifiers. The audible significance of tube… …
4Tube socket — Left to right: octal (top and bottom view), loctal, and miniature (top and side view) sockets. An early transistor socket and an IC socket are included for comparison. Tube sockets are electrical sockets into which vacuum tubes (also known as… …
5Video camera tube — In older video cameras, before the mid to late 1980s, a video camera tube or pickup tube was used instead of a charge coupled device (CCD) for converting an optical image into an electrical signal. Several types were in use from the 1930s to the… …
6electron tube — an electronic device that consists, typically, of a sealed glass bulb containing two or more electrodes: used to generate, amplify, and rectify electric oscillations and alternating currents. Also called electronic tube. Cf. gas tube, vacuum tube …
