## Discrepancy

FLIGHT 970, PHL-BOS - ON TAKEOFF ROLL, ENGINE NR 2 WENT TO RSV POWER.  AFTER TOGA POWER WAS ENGAGED THE NR 2 N1 SHOT PAST THE SELECTED POWER SETTING, NR 1 N1 LAGGED BEHIND QUITE A BIT, WHEN BOTH N1 GAUGES FINALLY MET AT POWER SETTING, IT THEN WENT INTO TO-2 RSV POWER THEN WE REJECTED TAKEOFF.  MAINTENANCE  PERFORMED PNEUMATIC TASK, PERFORMED AUTO THROTTLE FUNCTIONAL PER 22-31-00.  REPLACED THRUST QUADRANT CONTROL.  OPERATIONAL CHECK IS GOOD AT THIS TIME.
