Not sure if it was mentioned, but Coolfungadget is now selling an OPA627 on an adaptor for cheap:

Also the Class A mod:

I think it is very honorable for him to mention that it is an easy DIY project and to provide links to the guides, while also selling it at a modest price for those who prefer to go that route.
 
 

 

so that 627 would just pop into the socket with no soldering or modding.

Yes, that should pop right in. Just make sure you have it facing the right way. You should line up the notch on the socket with the markings on the adapter.

The whoelsale price for 627AU is something like $18-20 each, so yes $10 for two is very cheap! I emailed JTam about this and he sent me pictures of the opamps, and of the results of testing resistance across the various pins with a multimeter to determine authenticity. They seem authentic, and the resistances check out, but I still don't know how he can sell them so cheap. I ordered some, haven't arrived yet, but I will compare them with my other 627AU ordered from Cimarron Tech ($48 for a pair on a browndog) when they do, and let you know if there's a difference.

OPA627 is a single channel opamp so you will need 2 of them on an adapter. Coolfungadget is selling them by the pair already mounted on an adapter so all you will need is 1 from him.
