The book describes methods for repairing radio equipment. In this regard, the principle of operation of all stages of the radio receiver, the purpose of the parts included in certain cascades are considered, calculations of elements, circuits and components of the circuit are given. There is no need to talk in detail about how rapidly modern radio technology is developing. Currently, there has been a radical revision of the schemes and design of radio devices. Multi-module circuits, film and molecular electronics are finding more and more applications. The most common radio receiver, not to mention stereo and color music radios, is becoming a very complex device. This imposes serious requirements on the technical level of radio mechanics, training, as well as equipping repair shops. The book is intended for specialists in workshops and television studios, and will also benefit radio amateurs interested in repairing radio equipment and increasing knowledge in the field of electrical and radio engineering both independently and in the courses of radio mechanics.
