I need a Sound / Power Card for my PowerBook G4 15 inch AL. Model A1138. This was the last 15 Powerbook G4 made. The part number from the board is 820-1820-A.
Thanks, John

I think I paid less than $30 for mine on eBay, but that was two or three years ago. They're fun to install (in sartalics).

I have one. PM sent.
