[Coco] Coco .... having bad luck with Jameco components

[RJRTTY at aol.com]

Hello,
I have gotten  two bad 10 piece batches of 5 volt voltage regulators from 
Jameco which
is  holding up production of my RGB converter.  And they were different 
brand  names too.
I have ordered another batch tonight and we will see how they turn  out.

Has anyone seen this kind of thing  before?   What would cause such a 
cross-brand
failure like  that?
