I recently had one destroy itself on an HP 16717a logic blade. Burned all of the
way through the pcb, great fun. I guess that was early 90s vintage.

I forgot to comment on hermetic solid Ta caps. I have seen only a few failures of these over the years, and I consider them among the best of parts for reliability. I have seen lots and lots of failures in all kinds of non-hermetic Ta caps, especially certain brands of dipped style. My experience here is with the older parts in the same vintage as most of my gear and such, so not so much about more modern parts which should be better. For instance, I have seen very few failures in surface mount style solid Ta types that are so common now. These are non-hermetic but seem to survive OK. Or, maybe after these rack up many years they may degrade like the others. Only time will tell.
