Just checking - is it possible you were using a 9v AC power supply, rather than DC?
The last thing I'd want is to ship you a new board and have that blow up as well.
Obviously while I'm happy to replace any boards that were shipped to you defective, if it turns out that a board was shipped to you perfectly ok and was then broken by something you did I'd want to charge you some discounted rate for a replacement so that I don't lose out.
