Radio tubes (electron tubes, electronic tubes, vacuum tubes) and valves are just a part of radiomuseum.org. The other part is old radios. But we don't only list data for radio tubes or radio valves. We list data and pictures of tubes and valves of all types such as those for television, industrial, military and scientific purposes. You will find many forum posts about tubes and also data from reference manuals, tube specifications and valve data in English and also in other languages. You will also see many pictures of tubes, historical radios and other electronic equipment related to radio and tubes. Join the Radiomuseum if you are interested in tubes and valves - or in antique radios. Click the "Tubes" tab.
