Vacuum Tubes (1943)

The video explains the operation of the vacuum tube, specifically the triode, which is essential in modern communication devices like radios and telephones. It describes how a tungsten filament emits ...
A major scientific development, which will mean the saving of thousands of dollars worth of electric power annually through increased efficiency of the vacuum tube, or "electric valve," in controlling ...
If you work on simple digital projects, just about any bench supply will offer the voltage and current you’re looking for. However, if you’re working with valves, you’ll often ...
In today's world, vacuum tubes or radio valves seem as dead as high button shoes and buggy whips, but DARPA sees them as very much the technology of the future. As part of a new program, the agency is ...
The vacuum tubes used as power amplifiers in microwave systems may be on their way out following the development by a research team from US-based Agere Systems of a solid-state microtriode that can be ...
