Here's one project I've been working on:
www.telusplanet.net/public/dulan/DaleJE990.zip
Note: I subbed in BC550C and BC560C transistors because that's what I had, and the outputs have been set for the B - C - E pinout, I used a 2SC3940 and 2SA1534. I have not done audio listening tests through it yet, but it does do a pretty good job at a square wave from a signal generator at unity gain. Enjoy!
Oh yes, it is in the same package and footprint as the API2520 so you could interchange them.
