MANAGERS AND PROJECTIONISTS 1043 Amplifiers and Their Care NOTE. — This applies to amplifiers of all equipment dealt with in this book. IT is of course essential to the production of good results that the amplifiers and the amplifying system as a whole function perfectly, which means that the amplifiers must be cared for and kept in as nearly perfect condition as possible. Under the title "The Vacuum Tube as an Amplifier'' I have tried to give you an understanding of the fundamentals necessary to the intelligent consideration of such troubles as may arise in connection with amplifiers. When we understand in just what manner the vital parts of an equipment functions, we are in position to deal intelligently with troubles which may arise in connection with it. The tubes, while they give a relatively very small amount of trouble, may, and very likely will, eventually give some. It is your job to be able to recognize those troubles or their symptoms, rather, and thus be able to deal with them before they become acute. The life of an amplifying tube is not reckoned in days. It is figured in hours of actual service, which will of course vary somewhat with individual tubes, though it is not supposed to, but will vary very greatly in accordance with the amount of abuse to which it is subjected.
