Apparently, the structure of the piano is good, no separation of = the soundboard, but it flexes a little excessively under moderate pressure of th= e thumb, pressing on the medium rib. The back of the piano is against an insid= e wall, no ducts within 4 meters with the exception of a return (usually harml= ess) near the ceiling, above the piano. </FONT></DIV> <DIV><FONT face=Arial></FONT> </DIV> <DIV><FONT face=Arial>I do not recall excessive heat in the house during m= y visit last March.
