Listers, <BR><BR>I tuned a Yamaha U-3 today, approximately 20=
years old. Everything on it was fine, except for the=
squeak/rattle that seemed to emanate from the jacks. I've=
experienced this on other Yamaha uprights, but have not been=
able to come up with a definitive reason for the noise. It=
seems to me as though it's the jack/jack spring interface.=
The customers haven't complained about it, but it drives=
me nuts. It's evident mostly on hard blows. =
<BR><BR>I'm sure many of you have heard this noise before, and=
probably most of you have figured out what it is and have been=
able to fix it. If you have, please enlighten me! I=
will be forever in your debt! <BR><BR>Thanks in advance,=
