I have searched everywhere and even emailed Alesis to try and find a schematic for the power section on a DM8 module. If anyone has a link that would be great, or if you actually own one and wouldn't mind opening the case to take a pic of the area behind the power jack. I know I am missing a capacitor there and I suspect the blown out component may have been a diode. If I knew for sure, I think I could suss out the rest of the circuit and maybe save this guy from the trash heap.
