I believe there is a confusion over what this thread is about. What I have posted in the first post are gerbers for a pcb that will make it possible to use a regular 8 pin single IC opamp in a 2520 footprint.
The reverse is also something I've considered but have not done yet.
Well, this is finally coming down the pipe. Just the DIP8 and SOIC version for now.
This is what I posted in my WM thread:
Simple IC to DOA adapter PCB and KIT:
I had made the layout available for free to forum members a while ago and never really had a use for it. The need for this handy little PCB came up while prototyping some recent projects so I got a few made. They work great in an EQ I've been working on.
