Claude Paillard, F2FO, a radio amateur since 1959, shows here the various stages of the construction of a three-electrode (triode) valve. This valve made it possible to establish connections with other radio amateurs located on 4 continents. If you wish to know some more, visit his personal Web site (written in French). The video also contains shots of the valves in use.
