## Discrepancy

NR 1 ENGINE EPR INDICATION WAS BELOW NORMAL ON TAKEOFF, TAKEOFF WAS ABORTED.  THE AIRCRAFT RETURNED TO THE GATE.  MAINTENANCE REPLACED THE EPR TRANSMITTER, CHECKED THE PT7 SYSTEM FOR LEAKS AND THE INDICATOR FOR ACCURACY.  SYSTEM OPERATION WAS NORMAL ON RUNUP.  AIRCRAFT RETURNED TO SERVICE.
