Measure front and rear downbearing in several places in every section of the scale - especially in the killer octave area. Measure crown between all ribs. Play the piano - how does it sound? Is there a bad killer octave area? What do other areas of the scale sound like? IMHO, if you have no audible killer octave area and good overall soundboard function and reasonable downbearing and crown everywhere, you might have good results with the original soundboard. If you have an audible killer octave area or other bad areas and no crown and no downbearing, you are pretty much guaranteed you need a new board. If it sounds good, but you are lacking downbearing and/or crown, it's going to be a crap shoot if you don't replace the board. And if you need any recommendations on where to go to get the soundboard replaced, I could probably give you a name.....
