Weird ringing - HELP!!

[Terry Jack]

Thanks for the idea but I have checked it. I am guessing the problem is one of those very simple things staring me in the face and I can't see the obvious.

  Terry, This may be just too simple, but have you checked the sustain pedal to see that it is not lifting the dampers a tad?

    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!!
