UPDATE: I'm picking up where i left last year. Read here: http://groupdiy.com/index.php?topic=55946.msg768092#msg768092

I was looking around for a small-ish circuit to make a compact multi-channel preamp box, and stumbled upon this over at gyrafs site: http://www.gyraf.dk/schematics/Amek_2500_micamp.gif
Not too complex, fairly low parts count, no obscurities yada-yada..
I've redrawn it in Eagle: https://docs.google.com/file/d/0BxbSxLy_O-iOWFZxbVF3RVUwY2c
A second set of eyes would be appreciated - just in case
I'll be adding connections to add phantom power to the schematic, otherwise leaving it as is. No bells and whistles needed here...
If everything goes well, I'll make a shared project on OSHpark. My preliminary design sketch implies that the boards should fit vertically inside a shallow 1U rack case at 40x60mm, and the price would be about $18 for three boards shipped directly from OSHpark, in case anyone else would be interested
Does anyone have experience with this circuit - good or bad? Cool mods? Whatever?
Peace out // grrrunge
