## Discrepancy

AT ALTITUDE, THERE WAS A STRONG ELECTRICAL SMOKE SMELL IN THE FIRST CLASS SECTION.  THE SMELL WAS ISOLATED TO AN AIRPHONE UNDER-SEAT AUDIO BOX.  THE AIRPHONE CIRCUIT BREAKER WAS PULLED AND THE BOX WAS REMOVED AND PLACED IN A PLASTIC BAG IN THE COCKPIT.  BOTH CABIN RECIRCULATING FANS WERE TURNED OFF WHEN THE SMELL WAS DETECTED.  REPLACED TELEHPONE'S UNDER-SEAT TELEPHONE BOX AND CHORD REELS AT SEATS 1A/B.  OPERATIONAL CHECK WAS NORMAL.
