Please review the Table of Contents and additional information contained in the photos for an example of the content. These manuals contain photographs, descriptions, diagrams, and other pertinent technical information for each electronic tube contained in the index. (Please be advised that some of these pages placed on eBay did not scan properly and have a white line through some of the text. Therefore, these scans are not representative or of the same quality as the original documents that you will be provided in this publication). If you work on vacuum tube devices containing vintage vacuum tubes, these manuals can be indispensable. In addition, it is almost impossible to find them in a clean hard copy.

These pages are full 8.5 by 11 size loose-leaf, double-sided copies. Shipping is only within the continental United States, is at my cost, and will be shipped via USPS media mail.
