Depending on what you mean by << Bonk >> ... it sounds like hammer
blocking to me. Play the key of one of those Bonkers and hold the key down
while looking at the hammer. Is it up against the string, or is it checked
by the back check about 15 mm away ?

I have ran into several pianos that all have the same problem, which I
believe is caused by something that may require major repairs, but I am
at a loss as to what the real problem is. The problem is this. You can
play all the keys to check all the notes, and you'll come to a section
of notes that won't play. The hammer hits the string, but the only sound
it makes is, BONK! The strings do no resonate as they should. You can pluck
the strings, and they sound okay. You can hold the damper off the strings,
but when the note is played, the only sound it makes is, BONK! It sounds
almost as if the hammer is hitting wood, instead of the string. This is
only i<span
class=400250821-14062003>n</span> a section of notes, and
in the case of the U1 I inspected today, it was a little over an octave's
worth of notes in the upper tenor section, just before the treble break.
All the bass and all the treble was okay.</span><span class=390222716-13062003>
Is this a problem with the bridge somehow? I have seen this problem where
only two or three notes are affected, and another piano where the entire
tenor section was dead, and I have had no solution. I feel bad that I have
studied and been in the practice for so long, but have no solution to this
problem. Can <span
