These are manuals that were provided by libraries or may have been part of the archives of major electronics service centers. They are not the same as or equivalent quality as factory service manuals and may present as photocopies. Prices reflect that. We are selling them as they were received, and cannot verify or guarantee that every page is 100% legible or even that they are complete. We are offering them at discount prices rather than throw them out as we believe someone out there might find they still have some useful information. However we are selling them as-is. In the event that a buyer is unhappy with their ex-library purchase, and IF we happen to have that same manual in PDF (through AnalogAlley.com) or factory paper format, we might be willing to credit the purchase price towards the cost of a replacement PDF or factory paper manual, but no credit will be provided for shipping charges already paid or due on new purchase. If quality is a concern, we highly suggest you purchase either a PDF manual or factory paper manual instead.
