This 2-volume set offers invaluable knowledge. Volume 1, 'How to Fix Transistor Radios & Printed Circuits' by Leonard Lane, published by Gernsback Library, Inc. in 1961, is a great resource. Volume 2, 'Wiring Simplified' by H.P. Richter, from Park Publishing, Inc. in 1968, is in its 29th edition. The books are in acceptable condition. They have moderate soiling on covers, tarnishing on text block edges, some writing in 'How to Fix' without affecting readability, yellowed pages due to age, and stiff but secure bindings.
These books are perfect for anyone interested in fixing transistor radios, understanding printed circuits, or simplifying wiring. To use them, just start reading from the beginning to get a comprehensive understanding. As they are old books, handle them gently to avoid any damage. When you're not using them, store them in a dry and cool place to prevent further yellowing of the pages. If you write in the books, use a pen or pencil that won't smudge to keep the text clear.
