Roger beat me to the punch about the rim. :-) I once had this kind of 
problem with a Bose in a private home. I tried everything I could think of, 
to no avail. Everytime I went to tune it, it needed at least a partial 
pitch raise.

Since I knew the house had one, I finally asked how long it had been since 
the climate control system had been checked. He said quite a while, so I 
recommended he have that done. He did. It wasn't working. Was repaired. No 
more tuning problems! I found out about the rim later when talking to Roger 
W. @ Bose/Kimball.
