Can anyone help me confirm whether these are real or fake opa627ap's? i bought these a few months ago from a seller on ebay selling them as used and told me they came from a vintage reciever or something i forgot, they're from a 1992 batch i believe according to him, does anyone know?

I wasn't able to find anything about this seller anywhere on the internet, but I'm pretty sure he is trustworthy now (and cheap as hell, I might add). atsmile.gif

thats who i bought mine from, i'm not knowledgeable enough to say if they are authentic or not, but they do sound good and warm which is what i was expecting from them and looking through his past sales and stock of whats currently on sale, it seems legit but i just would like piece of mind

Bit late to this thread.

I have received many 627BP's from http://www.ebay.co.uk/itm/1set-Dual-to-Mono-Op-amp-OPA627BP-OPA627-replace-NE5532-/261019559217?pt=LH_DefaultDomain_0&hash=item3cc5fa6531 they have always tested "true". I only took one chip out of the adapter to test...it was about 59.k pin 1-5 as has been the case on previous occasions from this particular seller...just thought you might want to know.
