[pianotech] Old Kranich and Bach Grand

[Clark Sprague]

Thank you Paul and Mike.  I know that Ed Sutton is right when he says that 
the regulation needs to be addressed first, if any successful repairs are to 
be done.  I was hoping to just get rid of the problems, but judging the 
replies that have come in, this just isn't going to be in the cards.  Unless 
there is someone out there that can enlighten me on the question, is there a 
source of replacement parts, or is it feasible to alter what is out there to 
make them work?
     Wim suggested just replacing the jacks, and the only thing about that, 
is that there is a little protruding piece on the back of the jack, that 
holds the butterfly spring in place.  I would have to deal with that; maybe 
that is not so big a deal?
