Just to add a little more spice to your T/O power setting -
On the '74 Classic, it's the FE who follows-up with the power levers, and calls 'power set' and calls 'throttle hold' (when indicated), and increases the thrust on the PFs call during an engine failure on T/O.
Also, be aware, if not already so, with these types of auto throttles, if the T/O is aborted prior to 'throttle hold' indication, and the power levers are retarded to idle, the auto throttle system will continue to try to advance the power, very quickly, when you remove your hand from them, and that can be very embarrassing indeed.
The fix, always disconnect the auto throttle when you retard the power levers during an abort, one less thing to think about!
Cheers
