John I am getting sympathetic sounds from the undampend section of the high treble. As I mentioned in my previous post, if I press against the damper itself, nothing is happening to the offending strings, however if I press against the strings with my finger the racket stops.

Sounds like there is a bass string that is sounding sympathetically with some higher strings. After you hear the ringing, try putting your hand on several low bass strings at a time to see if that makes it stop. If that's it, you'll have to adjust the offending damper(s).

I have been working on a Farrano Pian Co. 54" upright S/n23990 pre 1910. At this point it has been tuned. I made the mistake of tuning it 20 cents flat as the customer said she was concerned about it being so old. I have also done numerous minor repairs, shaped the hammers, replaced the damper felts and given it a minor regulation. The piano has developed a strange "after ring" in random notes in the mid treble down into the single bass strings. Even if I press on the new damper felt it continues! I have checked the damper regulation (timing seems fine, lift ok and if I press on a string the damper follows nicely. I've done the basic string checks ie, seated at the bridge, bridge pins, checked to see if the sound changes at the capo bar if I gently press a brass rod agains the string sideways etc. The plate is tight to the tuning pin block and the ribs are tight, I can see no cracks in sound board, nothing has fallen down between the plate and wooden parts front or back. I have removed pictures off the walls, items off nearby tables etc. I even had a fellow RPT look at this instrument and we can not find the trouble. she did make a couple of recommendations and I have done those. they included checking the spacing of the hammers (again) and gently reshaping the hammers. I have one thing I am going to try yet. I see no reason not to tune this piano to A440. I have discussed this with the owner. After literally spending all day in her not air conditioned house in this 100 + weather here in Oregon I gave up for the day. I am totally stumped. sure would appreciate some insite from you guys and gals!!
