I still have the old keys from the "86 C3, they were barely 3 years old and Yamaha told me to throw them away! Except for being gray not white they were in excellent shape and I couldn't bring myself to do it. I repacked them in the box they shipped the new ones in and I've had them ever since!  </DIV> <DIV> </DIV> <DIV>Just call Yamaha with the serial number and they will tell you. If they are in that group they'll send a shipping box and an address to ship them to. Figure on about 2 or 2 and a half weeks downtime for the piano. The person that recovers them doesn't remove any wood from the keys so there is no adjustment to be made just removal, packing, shipping and replacement. At least that's what they claim, I'm shipping after Christmas, I'll let you know.  <grin> </DIV> <DIV><BR clear=all>Mike<BR>-- <BR>People who say it can't be done, should not interrupt those of us who are doing it.<BR>Michael Magness<BR>Magness Piano Service<BR>608-786-4404<BR><A href="http://www.ifixpianos.com/" target=_blank>www.IFixPianos.com</A><BR>email <A href="mailto:mike@ifixpianos.com" target=_blank>mike@ifixpianos.com</A> </DIV></DIV></DIV></DIV></DIV></BLOCKQUOTE></DIV> <DIV><BR>I was holding out for that day when I needed to rebush a set and could use these as interim forgetting of course that I still would have no sharps!</DIV> <DIV>So I've decided to use them for riblets, nice spruce and in some cases I can leave the weights in for mass loading the sound board!</DIV> <DIV><BR clear=all>Mike<BR>-- <BR>People who say it can't be done, should not interrupt those of us who are doing it.<BR>Michael Magness<BR>Magness Piano Service<BR>608-786-4404<BR><A href="http://www.IFixPianos.com">www.IFixPianos.com</A><BR>email <A href="mailto:mike@ifixpianos.com">mike@ifixpianos.com</A> </DIV></BLOCKQUOTE></BODY></HTML>
