The last stage of this circuit has a gain of 10 when the gain pot is full clockwise.  If this is not enough, you may have a build issue.  Please check the values of all installed components.  If you don’t find any mismatch, then post good photos of both sides of the board as well as a photo showing all wiring connections.
