I suggested that the hammer = bushings around their center pins may be swelled due to humidity resulting in = tightness and friction causing the slow motion return.  He had a heater bar = in the piano and I suggested that he plug it in to dry up some moisture. He = did. Two weeks later he calls and tells me it only helped allittle and the thing = is still unplayable.              = I am thinking that the only thing left to do is to bring the action home and = put it near a radiator so they dry out, and give each pin a shot of protek. Any = other suggestions? thanks, Julia Gottchall, Reading, PA </div> </body> </html>
