Rendis, checking the schematic right now, but those components are not visible on the schematic for the A1278 any chance you could give us either the logic board number or the last three digits of your serial number. It will help to properly identify your board

Rendis, both of those are capacitors. Readily available at any electronic warehouse like Mouser.com or Digikey.com. They are part of the Audio amplifier circuit. :"

C6607 1UF 10% 10V X5R 402 Package

C6611 0.0027UF 10% 50V CERM 402 Package.
