Good Luck!

Admittedly, it has been years since I was last asked to look at a Pearl =
River, and it was a most frustrating experience to say the least.

Sluggishness.  Is it in the keys themselves, or in the pinning of the =
action parts?  Any kind of sluggishness will affect the touchweight of =
any key.

If that sluggishness is in the pinning, is it simply tight pinning, or =
is there a problem with corrosion or abrasion on the pins?  Or is the =
sluggishness coming from poor-fitting parts, such as the birds-eyes =
binding against the inside of the flange openings?

In the case of binding parts, I've often found too much felt from the =
bushing protruding into the opening and causing the part to bind.  A =
very sharp razor or scalpal blade is best for removing this excess in a =
procedure I call "shaving the armpits."

Now that all of the parts work properly, how is the engineering?  It =
could be that when all is said and done, the keys still play like a row =
of 2x4s unless you have the option of redesigning the action.

  Hi all,
  I have been asked by a local dealer to regulate some Pearl River =
uprights.
  The pianos exhibit very high down weight and  are very sluggish. I did =
not have the time to examine them closely to diagnose the reason but was =
told by the dealer that many of these pianos are comming in with these =
symptoms.
  Any one have any clues what to look for?
