Poor sound from g#6 up

    Greetings all,
    I just went to tune a Yamaha M23 from 1984 which exhibited a problem which, as usual, bothers only me. The customer, a beginner, said she had really wanted an Everett she had seen in a shop (I think only from name recognition, go figure...) but this had been cheaper from private sale. I looked up the serial number and said "congratulations-you still got an Everett!"

    The piano was in nice condition, but I noticed that as soon as I hit G#6, there was more of a thunk with no sustain. None of the notes above had any sustain either. There was no visible discontinuity in the hammer line, and I didn't observe any other obvious faults, such as bridge separation. No reason to be new hammers, which were grooved as one would expect for this age. C8 had no real pitch.

    My gut feeling is that the hammer line is too high-is that the likely cause? Is bending the post a viable fix?

    On my Yamaha P2 a note will thunk if the spoon on the back of the whippen
    is missing or mis-aligned.

    You can adjust the spoons by reaching under the key-board with the fall
    board removed.
