ATTENTION!: THIS IS A CD, NOT A PHYSICAL/PAPER BOOK!!! ABC of Vacuum Tubes in Radio Reception by E. H. Lewis 1922 PDF on CD (Pages 88, 89, 114 and 115 have been added at the end of the book, but this does not affect the usability of the book. Overall the book is 100% complete.) CD Contents: ABC of Vacuum Tubes in Radio Reception by E. H. Lewis (1922): 134 pages Format: PDF IN ZIP, Language: English "AN ELEMENTARY AND PRACTICAL BOOK ON THE THEORY AND OPERATION OF VACUUM TUBES AS DETECTORS AND AMPLIFIERS. EXPLAINS NON-MATHEMATICALLY THE FUNDAMENTAL PRINCIPLES UPON WHICH ALL VACUUM TUBE CIRCUITS ARE BASED. INCLUDES PRACTICAL CIRCUITS AND PRACTICAL QUESTIONS AND ANSWERS. IT IS WRITTEN ESPECIALLY FOR THE BEGINNER. ALL ELECTRICAL AND RADIO TERMS ARE FULLY EXPLAINED."
