Two or three notes stick only when the damper pedal is used. I have checked the damper lever felt for indentions and there OK. Briddle strap wire is clear. Key dip is the same as other keys.  I checked a few other things that another Tech suggested but nothing seems to stop the sticking. Any ideas will be appreciated.</STRONG></P> <P><STRONG>Dick Powell</STRONG></P> <P><STRONG></STRONG> </P></BLOCKQUOTE></BODY></HTML>
