John,

There's this neat little chart from Wikipedia (they have a pretty good 
write-up on the Boesendorfer pianos too, better I think, than the company's 
website.

Model Length Keys
130CL Upright 88
170 5' 7" 88
185 6' 1" 88
200 6' 7" 88
214 7' 88
225 7' 4" 92
280 9' 2" 88
290 "Imperial" 9' 6" 97


I just finished installing a DamppChaser system in a Bosey 290 Imperial. 
NOT a fun job!  The DC company said it would take about 2.5 hours to 
install.  Now, I know I'm getting up there in age (63) and slowing down, but 
it took me 6 hours!  The first four components I installed all had to be 
done differently than DamppChaser's layout said to do--they wouldn't fit.

Now I can't wait to see if it stabilizes the piano.  it has been all over: 
way sharp in summer, fall and early spring and flatin the latter half of 
December.

I will check my tuning graphs and see if it has the unusual patterns you 
have described.  I measured and graphed the tuning before I turned the 
system on last Thursday and will do so again either Wednesday or Thursday 
this week.

 It goes out of tune more wildly than
other pianos. There are huge RH changes in this church sanctuary, so huge
changes are to be expected. However, some sections do the opposite of what
every other piano does: the first treble section (maybe from around C5-F6)
is generally the complete opposite of what the tenor will be. E.g., last
week I tuned it: tenor was 10-15 cents flat, and the first treble section
was 5-7 cents sharp. Do they all react this way?
(And I've recommended and recommended a Piano Life Saver system ... to no
avail. So if they want a piano that sounds like crap half the year, I guess
that's their business. <G>)
