Make Your Own Tube Testers and Electron Tube Equipment

This book shows audio connoisseurs and amateur radio enthusiasts how to construct and use their own vacuum tube testers. In addition, it describes how to make electron tube equipment, how to design high voltage supplies, how to work with metal, plastic, and glass, and more. The reader can make a shiny new tube tester that produces laboratory-quality results for a fraction of the price of a worn-out vintage tube tester.
