OAKLAND, CA, UNITED STATES, July 9, 2025 /EINPresswire.com/ -- Ray Tubes is pleased to announce that its new-production vacuum tubes are now available through its ...

Talking about vacuum tubes in 2025 might seem like talking about the role of buggy whips in today’s transportation world; but that’s not the case. There’s no denying that these devices—called vacuum ...

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 ...

Given appropriate models for vacuum tubes, circuit simulators such as SPICE make analysis based on such nonlinear models a tractable effort. The Langmuir, Leach, and Koren models are discussed for the ...

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, ...

In February of this year, we reported on the China Aerospace Science and Industry Corporation, and its phase one testing of a low-vacuum-tube hyperloop-style maglev ultra-high-speed (UHS) train. In ...
