Summary
| Description |
English: An early vacuum tube radio receiver circuit used with the Audion (triode) vacuum tube which was invented by Lee De Forest in 1906. It uses a single triode as a grid-leak detector which rectifies the radio signal from the antenna, extracting the audio modulation (sound) from the radio frequency carrier wave, and amplifies the recovered audio frequencies. |

This circuit image could be re-created using vector graphics as an SVG file. This has several advantages; see Commons:Media for cleanup for more information. If an SVG form of this image is available, please upload it and afterwards replace this template with
{{vector version available|new image name}}.
It is recommended to name the SVG file “Single tube triode receiver circuit.svg”—then the template Vector version available (or Vva) does not need the new image name parameter. |
