What is a Vacuum Tube / Valve
Vacuum tubes or thermionic valves formed the mainstay of the early electronics industry. Now they are widely used in audio amplifiers where aficionados find the sound they produce very appealing. Find out how they work in our tutorial.

Electronics Notes aims to provide accessible summaries about a host of electronics, radio and connectivity technologies. Our aim is to support those who want to learn about the technology: those who ware established engineers as well as students and hobbyists.
The topics included in the site range from the basic electronics concepts (useful for established engineers as well looking for those equations, formulas etc) though topics like electronic components, construction and manufacturing techniques to items such as antennas, radio propagation, wired and wireless connectivity including mobile communications and a host of other topics.
To fund the running of the site, we obviously need to carry advertising, but we aim to make this not too intrusive. We hope you understand, but we need to have income to meet the not inconsiderable running costs.
