Do tantalums exhibit the same gradual recovery behaviour as electrolytics? My (albeit limited) experience is that they tend to short spontaneously -- when they don't decide to explode, that is. ;^)

Btw, one of the caps in my HP65's PSU reads 11 ohms ESR! While that doesn't sound right, I doubt it's the cause of the card reader woes. I checked the motor with my bench supply, and it's definitely a mechanical issue.
