I have no 78 RPM turntable so am recording the record to Amadeus Pro at 45 RPM and attempting to change the pitch/speed in A-Pro. I've arrived at 175% as the approximate correct increase in speed=time on 78 label.

My question:

If I select the LOCK, is the pitch correct when the speed is increased to 175%?

It should be. The calculation is ok.
I remember some discussions about recording 78's in the past. Maybe you could search the forum.

Will need to equalize the sound -- not quite sure how one would do it
with standard equalization curves.

Thanks for the answers. Guess I can always EQ to taste which may not be the best way. I do have good monitor speakers in my studio.

Thanks again.

More accurately, the rate should be 173.333, which is the result of 78 45.
I've used this same method to digitize 78s without a 78 player, and have
gotten some very acceptable results.

'Equalizer' from Brian Davies:
http://www.clickrepair.net/software_download/equalizer.html
can correctly convert from RIAA (the microgroove standard) - including at the wrong speed - to a specified 78rpm EQ. See page 11 of the manual. It's free.
