Narrative:
Aircraft had following outstanding maintenance carry overs -- altitude alert system, captain's indicator out, left elevator position indicator inoperative, aft airstair compartment service light system pops circuit breaker, right gear door indicator inoperative. Inbound crew wrote up both directional gyro/compass system for precessing. Captain's directional gyro replaced, first officer's checked out and signed off. In cruise, discovered 30 degree split between captain and first officer compass. Wet compass agreed with first officer. Flew first officer with wet compass backup to visual/ILS backup approach. All maintenance carry overs were institutes in ZZZ, our major maintenance hub. We are not fixing airplanes. They leave it up to the flight crew to deal with it. It made for a busy, late night -- even under normal circumstances.
