Hi,
I have this piano, Kawai PN80 since around 1998 and it always worked very good. In all this time, there was never need to repair anything, but there are two problems: one key makes a "plastic" sound when it is pressed (piano on or off), and one key is a bit louder than the rest.
I would like to sell it and have no idea what could the price be. Do you might know and is it possible that I could fix those two problems on my own?
Thank you for all the informations you give with possibility of comments!
Kind regards.
