All RF Cafe quizzes would make perfect fodder for employment interviews for technicians or engineers - particularly those who are fresh out of school or are relatively new to the work world. Come to think of it, they would make equally excellent study material for the same persons who are going to be interviewed for a job.
Some of these books used in quizzes are available as prizes in the monthly RF Cafe Giveaway.
Note: Many answers contain passages quoted from the text.
This quiz is based on the information presented in Make Your Own Tube Testers and Electron Tube Equipment, by Gary Steinbaugh.
With more than 30 years of RF engineering experience and Ham radio involvement, Gary has a very broad and deep proficiency in electronics. His new book, Make Your Own Tube Testers and Electron Tube Equipment, is a great assimilation of his personal knowledge and includes some of the highest quality line drawings and photographs of any technical book I have ever seen - and I've seen a lot of them! The preface section is also unique in nature, followed by a short history of and basic circuit design principles for vacuum tubes. Gary also conceived of and built a 3-dimensional physical model of the plate, transfer, and constant current characteristic curves for a typical vacuum tube (6SN7); you've never seen this before. The homebrew tube tester and power supply projects described in the text and built by Gary are exceptional examples of craftsmanship.
1. Which of the following are negative properties of vacuum tubes?
