I recently bought a Bose QC15 display model that was modified to take 12v  and i am trying to figure out how to convert it from the 12v dc to 1.5v dc. Can't seem to find the where the original battery leads went, any help is appreciated but a picture of the board under the RIGHT left ear cup would be the most helpful.
 
EDIT: need a image of the RIGHT side not the left.
