Opamp Burn-In?

[petemoore]

I got some OA's that were 'burned in'....[also Up and Out]
 You can have 'em for shipping and handling.
 Some are already branded/piggybacked...
 Others output LOTS of heat at some point in their history, to the point where you can't touch 'em...I don't theink theres a working OA on this earth that got THAT hot.
 I have some other OA's, with a dead guys fingerprints on them too...this makes them one of a kind, no other opamp will perform, when dusted for prints, like these do.
