If they're in metal cans I'd just sell them; they're not that quiet and people think metal cans have Mojo...

It's a dual op-amp but I couldn't find any datasheets on it.

Googled it, found a few sites that mentioned it.

Hi Rocklander,
uA 741 is a single package Opamp (different pinout to dual)
sn7274 might be a dual opamp. A pic might help you discover more?
How many pins? what shape is it?
Phil.
