Bob, Obviously you didn't read my post thoroughly. I said that I work on ENGLISH pianos, 100+ years olde and the worst of the worst that England has to offer. These instruments were "rejected" by English technicians and were sold to American "Antique" dealers. Yes, most of the English uprights of that period, unfortunately, were 3/4 plates, (Why England was soooo far behind everyone else in the world, in this respect, is beyond me). These are precisely the instruments that I "Specialize" in. (Most Technicians on this side of the "Pond", think I'm nuts to do so. I do pitch raise those instruments to their "DESIGNED PITCH", which was 435cps, (or as you put it C517). I do this with little or no problem. By the way, 435cps is 20cents flat of 440cps, NOT a 1/4 tone as you state. When these instruments are at their DESIGNED PITCH, (ie the pitch that was used in the initial design of the scale), they have less damper problems, less tuning stability problems and sound a helluva lot better than you can imagine! This I have learned over the last 28 years of working on them. So, I disagree with all that you have said about Over-Damper pianos! Respectfully, Joe Garrett, RPT, (Oregon)
