Well I received a shipment of boards from batchpcb recently. Problem is I noticed that the solder pads on the bottom of the PSU boards are totally covered in solder resist. Thankfully the amp boards are fine. I'm pretty sure the mistake isn't on my part (I double checked that batchpcb's layers and the files matched up) but just in case these are the files I used: http://www.mediafire.com/?9fb9joxmabyx9b0
I'll probably send a polite email expressing my displeasure to batchpcb, but it doesn't hurt to check with others first. I'll take some pics tomorrow when I have time.
