THIS book was first published in 1937 under the title “The Low Voltage Cathode Ray Tube”, which was somewhat misleading in view of the fact that it deals with the various forms of cathode ray tube ...

Dim lights in order to make the electron beam more visible. Wire up the heater and accelerator contacts (and also deflector contacts, if desired) on the tube to the power supply (or supplies). If ...

Perhaps nothing added quite so much to the charm of vacuum tube circuits from back in the heyday of the vacuum tube as did the “Magic Eye” indicating tube. With the ghostly green glow of its circular ...

Linear, small-signal AC models can be useful in the analysis and design of vacuum-tube-based circuits. Under large-signal conditions, nonlinear models are typically required. Almost 120 years ago, ...
