It sounds like you just may have a bunch of cruddy capacitors (or a power
supply problem that is not killing the chips). I have never found a bad
tantalum capacitor.
Maybe my memory is a bit vague - but tantalums in the
1960's ??????????
They were around in the 1960s, but basically for military applications.
