I've been having a very high failure rate on corona assemblies on my 1350's and ProEx machines - to the point where for a while I didn't bother changing wires, I just kept an assembly handy for when they started throwing SC300's. Not sure if it was contamination from whatever paper stock they were using (different customers using mostly different papers) or the plastic used in the end caps was degrading. It's gotten better recently, but I still can't get a million out of a set of coronas without painting the inside of the terminals with teflon grease.
