Yeah, Gordon....

I'm one of the staff technicians at the Yamaha dealership here in =
Phoenix.   The first thing you should look at, believe it or not, is =
easing the balance rail hole.   Here in Phoenix, every piano that comes =
in from Yamaha needs it. If you can lift up the 16th of an inch or so =
before the upstop rail  stops your lifting, and it stays up, then take =
it apart and do them all.  This is enough to generate pass numbers =
(error reports) on their Disklaviers.  It also makes the piano feel so =
much more even and pleasant to play. =20
    Another thing you might also like to do is to put a drop or two of =
Protek CLP on each of the front rail bushings. You will end up being a =
real hero in the owner's eyes, believe me.

Kevin.

  Subject: Yamaha Colsole, Sharps checking on trill with sustain =
pedaldepressed.


  Hello List.  Yamaha P22, Console, 270499, owner bought new from local =
Mishawaka, IN., dealer three years ago.
  Dealer sent a "tooner" to tune 1st time, and owner call her back for =
2nd and 3rd tuning.
  On 3rd visit, the owner asked the "tooner" why the sharps would "stick =
or not return when a fast trill was played, with the sustain pedal =
depressed".  "Tooner" told the owner that Yamaha Consoles had this =
problem and said that it was probably the front pin bushing being too =
tight.  (The problem does not present itself when a trill is played and =
the sustain pedal is NOT depressed).

  Anyway, the "tooner" took a thin steel blade, probabaly a machinist =
rule, and jambed it down between the keys in the area of the front pins =
and moved it back and forth saying that she was trying to free up the =
space in the area of the pin bushings.
  I wonder if this "tooner" even knows where the pin bushings are =
located, surely not on the side of the key stick.

  The "tooner" did not remove the key slip to look under the keys to see =
if anything looked amiss.  "Tooner" could not resolve the problem and =
left.  Will not return calls made to her.  Owner has called the dealer =
several times and the dealer will not return the calls to address the =
warranty problem.

  The owner got my name from another satisfied customer of mine and =
called me.
  I looked at the piano this afternoon to play it my self and experience =
the problem first hand.

  Offending sharps are G#4, A#4, G#5, C#6, G#7.

  Does anyone have some knowledge to shed on this problem and what to =
look for and in what sequence.  What initially should I be looking for?

  Many regards to all.
