Narrative:

We were flight cvg to phl. As we spooled the engines to 1.4 EPR on takeoff, we got a takeoff warning horn. The captain rejected the takeoff. We taxied off the runway -- all conditions were normal -- the stabilizer was in green, leading edge and trailing edge flaps in takeoff position, the spdbrake in down detent. We spooled the engines up on taxiway -- no takeoff warning horn. We took off out of cvg -- no horn -- however -- no entry was made in logbook -- we didn't return to the gate.
