I don't remember the orange Spragues failing. It was good service practice to replace the white ones, whether they failed or not. Maybe some shops replaced the orange ones, just to be sure.
I was part-time and didn't handle the volume of work that many of the firms did. Some of the shops used to boast, 20 to 25 service calls a day, according to Electronic Servicing or similular magazines.
