<DIV><FONT face=Tahoma size=2> Yamaha MX100 w/Disklavier (U1)
6 years old, in a H.S. vocal music room, never moved from there. Climate
controlled year around. At the tenor/treble break the F#5 and G5 go out of tune
overnight! We've had trouble with this piano since new being unstable, but
its getting much worse now. Lovely instrument, sounds great when tuned,
but almost immediately goes flat around this brace. Measured all the
notes today after having pitch raised and tuned 9 days ago. SAT says all
notes within 2-3 cents except those mentioned and a few others here and there up
to 15 cents flat. Measured these again after finishing up today, and
they're 5 cents flat within 45 min. </FONT></DIV>
<DIV><FONT face=Tahoma size=2> Strings look good, bridge, pins
and hitch look fine, pins are tight and smooth, no plate separation from back,
running out of ideas. </FONT></DIV>
<DIV><FONT face=Tahoma size=2> We called the dealer who will
in turn bring Yamaha in now. Any thoughts?</FONT></DIV>
