You are now being introduced to a remarkably simplified technique of radio repairing. This new way of finding radio faults and repairing them is so revolutionary in scope, so different in application, and so effective in results, that one can hardly believe in its true possibilities. But this method will (in contrast to all other servicing methods) in 90% of all cases isolate the fault in minutes instead of hours and without instruments, permit checking of parts and circuits quickly without any special testers, and can be used to an advantage by beginners and experts.

The comparison technique of radio servicing tells you what simple tests may be made to obtain electrical, visual, and other reactions from radio parts and circuits, and how to determine if the indications secured are what is to be expected from a properly functioning circuit, or what parts or stage to suspect. This method is a great simplification of radio servicing and calls for less knowledge, less time spent, and less instruments.
