Counterfeit

Not money, but electronics.  Which in some cases can be even worse.


This is the main circuit of a OPA627 amp circuit.  On E-bay and a few other places there is a counterfeit being sold for a few buck.  A real one can set you back $20 and up.  But it's not worth it is.  The fake can do the job, but with higher signal noise and a higher voltage offset.

Fake audiophile opamps: OPA627 (AD744?!)

And remember, if it's too good to be true, it probably is.
