If your Philco Radiobar came with a 650 chassis, then it used the K-17 8'' speaker and not the 10.5'' H-13 speaker. The H-13 will work with the 650 chassis however if you want to cut a larger hole for it and remount. It does not appear either of those speakers would work for you and a 650 chassis.

Interestingly, the 660 should have an H-13 speaker as it is a 42 triode setup. Maybe someone else can weigh in on the part numbers. I don't see them in Ron's Speaker spreadsheet...
