This is for the complete 3 volume set of books tilted Home Audio Systems Schematic/Service Manual, all published in 1978 by Tab Books. All stated First Printing. Softcover. Volume 1 features models from Capehart and Zenith; Volume 2 features models from Coronado, Channel Master and Hitachi; and Volume 3 features models from Admiral, Automatic Radio, Midland and Sharp. Each volume contains 200 pages. Corner bumping to books, particularly to upper outside corner of Volume 1. Minor edge bumping to Volume 2. Interior pages are clean. Uncracked spines. Perfect bound, and binding feels strong, but care should be taken when handling to ensure the continued integrity of the 48 year old glue. Very nice examples of these great reference works!
