I replaced the action brackets on a Young Chang G-150 today. I recognized the problem because this was the 2nd piano that I have run into with it. I do not know the serial # range but this piano serial was 60394. We do not think of metal changing dimensions but it is not all that uncommon to see key leads swollen enough to rub on adjacent keys. Perhaps this is something like that. Norm Barrett Memphis, TN Carl Root wrote: > Dale R.
