The piano is probably 20 years old.  Well, I did a nasty and put a thin film of protek/Teflon on the bearing points, and think that helped a bit.  It’s as bad as some of the Chinese things I have had to despise- and for a Yamaha, which has been my favorite “brand” to tune, mostly because I did hundreds of P22’s in a school system, along with a bunch of C 7’s- but this piano is unique in my experience. <o:p></o:p></span></font></p><p class="MsoNormal"><font size="2" color="blue" face="Arial"><span style="font-size: 10.0pt;font-family:Arial;color:blue">Thanks<o:p></o:p></span></font></p><p class="MsoNormal"><font size="2" color="blue" face="Arial"><span style="font-size: 10.0pt;font-family:Arial;color:blue">les<o:p></o:p></span></font></p><p class="MsoNormal"><font size="2" color="blue" face="Arial"><span style="font-size: 10.0pt;font-family:Arial;color:blue"><o:p> </o:p></span></font></p> <div> <div class="MsoNormal" align="center" style="text-align:center"><font size="3" face="Times New Roman"><span style="font-size:12.0pt"> <hr size="2" width="100%" align="center" tabindex="-1"> </span></font></div><p class="MsoNormal"><b><font size="2" face="Tahoma"><span style="font-size:10.0pt; font-family:Tahoma;font-weight:bold">From:</span></font></b><font size="2" face="Tahoma"><span style="font-size:10.0pt;font-family:Tahoma"> pianotech-bounces@ptg.org [<a href="mailto:pianotech-bounces@ptg.org">mailto:pianotech-bounces@ptg.org</a>] <b><span style="font-weight:bold">On Behalf Of </span></b>Andrew Anderson<br> <b><span style="font-weight:bold">Sent:</span></b> Thursday, September 08, 2011 6:53 PM<br> <b><span style="font-weight:bold">To:</span></b> <st1:personname w:st="on"><a href="mailto:pianotech@ptg.org">pianotech@ptg.org</a></st1:personname><br> <b><span style="font-weight:bold">Subject:</span></b> Re: [pianotech] yamaha C6</span></font><o:p></o:p></p> </div><p class="MsoNormal"><font size="3" face="Times New Roman"><span style="font-size: 12.0pt"><o:p> </o:p></span></font></p><p class="MsoNormal"><font size="3" face="Times New Roman"><span style="font-size: 12.0pt">does it have to do with rendering?<o:p></o:p></span></font></p> <div><p class="MsoNormal"><font size="3" face="Times New Roman"><span style="font-size: 12.0pt"><o:p> </o:p></span></font></p> <div> <div><p class="MsoNormal"><font size="3" face="Times New Roman"><span style="font-size: 12.0pt">On Sep 8, 2011, at 5:34 PM, Leslie Bartlett wrote:<o:p></o:p></span></font></p> </div><p class="MsoNormal"><font size="3" face="Times New Roman"><span style="font-size: 12.0pt"><br> <br> <o:p></o:p></span></font></p> <span style="orphans: 2;text-align:-webkit-auto;widows: 2;-webkit-border-horizontal-spacing: 0px; -webkit-border-vertical-spacing: 0px;-webkit-text-decorations-in-effect: none; -webkit-text-size-adjust: auto;-webkit-text-stroke-width: 0px;word-spacing: 0px"> <div link="blue" vlink="purple"> <div><p class="MsoNormal"><font size="3" color="black" face="Arial"><span style="font-size: 12.0pt;font-family:Arial;color:black">I’ve been tuning a C6 for 7 years or more, and it has every time been h*** to tune, and a 3-hour job. Nothing will stay stable. I’ve been doing it every two months now for awhile and today was the second time I didn’t have to go through each string on second pass.  Is it possible that the agraffes have been ground so sharply that one can’t get a stable termination point?   I’m a decent tuner and have done some mean pianos, but this one has left me befuddled.  Any sage advice??????  I think it will be replaced by the first of the year, but I’ll still be dealing with it for some time.<u1:p></u1:p></span></font><font color="black"><span style="color:black"><o:p></o:p></span></font></p> </div> <div><p class="MsoNormal"><font size="3" color="black" face="Arial"><span style="font-size: 12.0pt;font-family:Arial;color:black">Thanks<u1:p></u1:p></span></font><font color="black"><span style="color:black"><o:p></o:p></span></font></p> </div> <div><p class="MsoNormal"><font size="3" color="black" face="Arial"><span style="font-size: 12.0pt;font-family:Arial;color:black">Les bartlett<u1:p></u1:p></span></font><font color="black"><span style="color:black"><o:p></o:p></span></font></p> </div><p class="MsoNormal"><font size="3" color="black" face="Arial"><span style="font-size: 12.0pt;font-family:Arial;color:black"><br clear="all"> </span></font><font size="4" color="black" face="Helvetica"><span style="font-size: 13.5pt;font-family:Helvetica;color:black"><o:p></o:p></span></font></p> </div><p class="MsoNormal"><font size="3" face="Times New Roman"><span style="font-size: 12.0pt"><u1:p></u1:p><o:p> </o:p></span></font></p> </span></div><p class="MsoNormal"><font size="3" face="Times New Roman"><span style="font-size: 12.0pt"><o:p> </o:p></span></font></p> </div> <div class="MsoNormal" align="center" style="text-align:center"><font size="3" face="Times New Roman"><span style="font-size:12.0pt"> <hr size="1" width="100%" noshade="" color="gray" align="center"> </span></font></div><p class="avgcert" color="#000000"><font size="3" face="Times New Roman"><span style="font-size:12.0pt">No virus found in this message.<br> Checked by AVG - <a href="http://www.avg.com">www.avg.com</a><br> Version: 10.0.1392 / Virus Database: 1520/3885 - Release Date: 09/08/11<o:p></o:p></span></font></p> </div> </div> </o:smarttagtype></blockquote></div><br></div></body></html>
