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, design high voltage supplies, work with metal, plastic, glass, and more. You 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.
