I received some prototype boards from the pc fab house last week for the 2520 smd op amp. This is what the project looks like now with the parts stuffed:
Haven't done extensive testing yet, just setup in a preamp. Seems to work well, though. I am running these on +-18V. I may be able to make this available as a "semikit" with all the smd parts installed. The user would need to solder in the through-hole parts and the pins. I just need to construct a "bed of nails" tester to test the partially stuffed boards.
I have also built a rack for housing the 512-style modules. Here are a couple of shots. The rack has a built-in supply that will provide up to 150ma to each of the ten slots. The rack is constructed from a surplus eurocard rack that I had. It required extensive modification.
