I opened up an HP counter of mine and saw the dreaded RIFA X2 & Y2 caps.
Out of an over abundance of caution I replaced them.
Looking carefully at them they appear to be in reasonable shape. There is some minor plastic cracking but it seems at odds with the horror stories you hear.
Those are the problematic ones. They will fail. The cracking that you see is the beginning of the failure. We've replaced dozens of them at LSSM, some having exploded while others had gotten close. They aren't "horror stories", it's a well-known and understood failure mode.
