UPDATE: AKG USA sent me 3 replacement screws for the the ck3 capsule for no charge and they fit perfectly, so my problem has been solved!
I know this is a a bump from forever ago, but thinking someone in this thread could help me.
Does anyone happen to know the size of the screws used in the ck1/ck3 capsules? I'm referring to the 3 set screws that hold the grille to the capsule
