Hi, Dave:
    Sorry, but no cigar.  But you're close.  
    Here's the answer.  The bridle tape has a reinforcement at the end, plastic or leather or whatever.  The bridle wire was almost touching the backcheck wire (same note).   The reinforced end of the bridle tape rubbed against the backcheck when the note was played, causing a squeaky sound.  The solution was to bend the bridle wire away from the backcheck.  Normally, you wouldn't think that the bridle tape end would pivot on the bridle wire, but in this case it did.  And because the tape was pinched between the bridle wire and the backcheck, it rubbed against the backcheck wire, making the squeaky sound. 
    Please note, the bridle wire wasn't touching the backcheck wire on the next note (to the right).  That is common, but wasn't the case here.
    The lady was VERY happy to be rid of that noise.

Paul,

Let me amend my previoius guess to "backcheck dragging on sticker wire."  The fix?  Regulate lost motion?

Was it bridle wire rubbing on backcheck?

Did the noise happen when the right pedal was down? 

I thought of a spoon with a spot of glue on it eating a hole through the damper lever felt, but that would probably clack before the hammer hit the string.

Hi Guyz-n-Galz:
    I had an interesting encounter with an Acrosonic the other day.  The customer complained about a click/squeak noise on some notes, which she clearly noted on a card.   I was unable to hear what she was hearing, but said that if we tuned the piano first, the noise might become more easily heard.  So, I did a double pass tuning, which sounded all right to me, and asked if she still heard the noise.  She played the notes which she objected to, and said the sound was still there.  We played around with the notes, until I finally heard something.  It was a noise, like a faint squeak, that appeared upon release of the key.  I was thinking the jack cushion felt on the butt was the culprit, but that wasn't it.  I removed the wooden sticker from the action and after a few minutes of fussing around with the wippen, found the source of the noise.  See if you can guess what the cause (and remedy) was.&nb!
sp; Hint: the jack had nothing to do with the noise.
