Vacuum tubes also choose time (from a handful of seconds to quite a few minutes) to “heat up” to operating temperature—an inconvenience at best and sometimes a serious limitation to their use. These shortcomings inspired scientists at Bell Laboratories to seek an alternative to the vacuum tube and resulted in the development in the transistor.
Vacuum tubes are fragile and in the long run have on out in support. Failure takes place in ordinary use both from the results of repeated heating and cooling as products is switched on and off (thermal tiredness), which ultimately causes a Actual physical fracture in some Section of the interior construction of your tube, or from degradation from the Qualities with the cathode by residual gases in the tube.
