Re: Further MMC woes.

["Garry F." <garryfre-at-xxxxxxxxxxx> (by way of Terry Fritz <twftesla-at-xxxxxxxxxx>)]

The part number on the substitutes seems to be the same as what I ordered,
but I know they are substitutes because they told me that they had
substituted others. I really doubt that they are good caps, however when
Terry gets the dead MMC, he will be able to determine what is at fault.
