How does a vacuum tube radio work
WebHow Tubes Work: Introduction to a short basic course on tubes: Vacuum tubes were used not only in radio, TV’s and broadcasting, but also in commercial radio equipment, telephone systems, two way repeater systems, test equipment, and in many types of industrial electronic equipment. Although transistors and now have taken over many of the jobs WebPull the old part and its loose lead straight up so you can identify them. Remove the lead still attached to the body from whatever terminal it uses. Install one lead from the new part, trimmed to length, to that terminal. Solder if that's the only connection, or bend the lead around the terminal.
