When the orange “tombstone” plastic encapsulated surface mount tantalum caps fail, they fail shorted.

Last year, while powering up a 9000/715, I saw one actually flame because I had the good fortune to have the case open. Fortunately, damage was minimal and i happened in have a partial real of an exact replacement.

I’ve had other tantalum capacitors fail, orange drop epoxy dipped, actually incandesce and shoot an glowing slug about 5 feet away onto the carpet.
