| An electron tube, usually made of glass, evacuated to such a degree that its electrical characteristics are essentially unaffected by the presence of residual gas or vapor. Tubes have been essentially replaced by transistors and other solid state semiconductor devices for amplification and rectification. Cathode ray tubes (CRTs) are still used as display devices. | An electron tube, usually made of glass, evacuated to such a degree that its electrical characteristics are essentially unaffected by the presence of residual gas or vapor.
