I have a chance to get a hold of some 1960-1980 TV service manuals and was wondering what year the cutoff is for usefulness/saleability.

Thanks

Larry

Usefulness-anything in that date range would count. Saleability? Not much demand for most of them, I'm afraid. The most wanted would be early/mid 60s color. Factory manuals would be the most desirable as there is a glut of Sams Photofacts.
