Even if you don’t need a Photofact to get your radio up and cooking, it sure helps to have that dial stringing guide when needed. You get to keep your hair! Plus, the parts information with arrows pointing to components and listing their value can come in handy. My aforementioned Stromberg-Carlson is full of Black Beauty capacitors, which you know will be bad. The color bands are pretty much worn off and the Sams saves a LOT of time over figuring out just which cap you are looking for on the schematic.
