Re: Any Geekgroup MMC failures out there??

FWIW, I only remember hearing about two anomalous failures.  One was Chris 
Roberts' MMC in late June-early July.  I think the one prior to that, which 
I think was probably winter/spring of 2003, was unexplained and dismissed 
as a rare manufacturing defect.  All of the other failures I remember 
involved poor construction (I can think of two off the top of my head) 
and/or deliberate overvoltages (John Dyer - I remember those Geek List 
posts in June/July 2001!).

I remember others, but don't know if those were the CDE 942 caps (the "Geek 
Cap") or some other make/model.

I would be interested to know what sort of runtimes the caps are seeing, 
too, even if guessed to an order of magnitude.
