I would love if we could collect digikey part numbers for these caps. I really could use a digikey parts list for the portable. I'd definately go tantalums though, from what i've been reading. I'm assuming they're all similar, and should be chemically similiar since the Great Capacitor Disaster of mid-2000s has passed. http://en.wikipedia.org/wiki/Capacitor_plague Britt -- ----- You received this message because you are a member of the Vintage Macs group.
