I just closed the musical I do the lighting for at the local HS every year. They have quite a few fixtures that are down due to either bad sockets or that I've stripped the sockets out of(Starpars) to keep other fixtures(Shakespeares) going. There have been 3 Shakespeare caps that the studs that hold the socket in place have either stripped the hole or snapped off in the hole. Looking to replace the whole cap assembly on these fixtures. Not having any luck finding them.
