In one of the SAMS Annual Index I have it indicates coverage of service data publications since April 11, 1946. The Howard W. Sams Photofact® service data features standard notation schematics, photos of the chassis, alignment data, tube charts, replacement parts lists, and even troubleshooting hints for radio, TV, record changers, hi-fi, CB, and what ever. Besides the Photofact® they have other publications for all sorts of home entertainment equipment. They also published many books on electronics and related areas. Check with me if you need a SAMS. I just might have it. If I do you will get an original. I will Priority Mail it out to you at a very reasonable price. I only take PayPal and USPS money order. I prefer PayPal. NOTE: I don't have very much SAMS data above Set 1180 (1970/71). That's the cut off of my interests. Shedradios.com for your SAMS Photofact.
You can send me an email. I will let you know.
