The service manual was very usable and clear enough to see the individual values of all of the components (unlike some of the service manuals I have gotten in the past from web sites similar to this one). The price was right and the information was greatly appreciated. It helped me with an otherwise very difficult repair. It was much needed and appreciated. A faster turn around on my order would be nice, but I understand the constraints on your staff's time. Thank you for your service.
