<DIV><FONT face=Arial size=2>I have serviced one particular Bosie =
200 in a one
of my contract schools since 1979. It was always going through =
contortions and
the soundboard and pinblock were a mess before the Dampp Chaser complete =
system
without cover was installed. That helped some when the thing was plugged =
in
continuously and maintained which was intermittent. Two years ago we put =
in a
new board and block and replaced the action too, yes dampers and some =
other
stuff too. Since then it has gone through contortions, athough the =
soundboard
and pinblock are not a mess and the climate control system was updated =
but no
cover installed (im still considering) yet. The maintenance =
intermittancy and
power cord issue continues,but I will say that when the plug stays =
in and
the bucket is filled and the tunings are one or two a quarter it doesn't =
stay
put too badly. It is better than before. The pin block was particulary a =
mess
when removed. Some stability in design was added. The board ribs were =
midified
slightly. But afterall I'd have to say that the biggest factor in why =
these
otherwise good pianos go out of tune more frequently in changeable =
climate
conditions,than say Steinways,is the rim construction. Oh yeah Roger's =
right.

<DIV><BR></DIV>Roger beat me to the punch about the rim. :-) I once =

how long it had been since the climate control system had been =

rim
later when talking to Roger W. @ Bose/Kimball. <BR><BR>Avery =

I’m not sure why but I think it has to do with the type of rim
construction. I vote for a full system (and more frequent =
tunings,
of course).<BR> <BR></FONT><BR><FONT face="Times New Roman, =

This piano has a Spruce rim. The soft wood is way more =

to humidity changes. So perfectly normal. Yes you =
are
correct in your advice. Full Damp Chaser System with =
bottom
cover, More tunings.<BR><BR>Regards Roger</FONT>
