any a you geeks build DOA circuits?

interested in some 6-pin 2520-style DOA--especially the OA-10 but could be others, and more in the future. anyone assemble and sell these?

When I saw DOA I immediately thought "dead on arrival" which is what a lot of Ebay gear seems to be lately.

The last time I made a DOA was back in the 70/80(?)s based on LM394.

Now we can buy off the shelf op amps that are better and a lot easier.
