I decided to buy and share this book online as I found the internet was lacking in VCR servicing information. VCRs are still in use for a variety of projects and personal use, yet when they fail they are replaced. This book is compact and easy to read, and while not a specific service manual it does a great job of explaining the technical aspects of VHS. Even I understood a few concepts! Worth a scroll through.
