G'day Richard, Sounds like a typical example of duplex segments that are too long. If that's the case, the pitch produced by these can be within an easily audible range... the effect is to double the number of strings vibrating in sympathy in the top end of the piano. Trouble is that many of the duplex (particularly front duplex) are untuned and produce lots of odd harmonics, hence the cymbalish nature of what you are hearing. You can check this by plucking the front duplex...what you should hear here is the same note as the speaking length on the other side of the capo bar...this is good, it's doing it's job. But if you can hear another strong note that's not related to the speaking length pitch, it's the note being produced by the duplex in it's own right. Ron Overs from Sydney, posted earlier this year on a fix he did on a Grotrian concert grand with the same problem...check the archives.
