	Maybe you know, but I doubt the average reader on this list knows.  
That's why I go to the trouble to write posts like my last one (I  
usually write with the whole list in mind, not just one particular  
person). I don't like the idea of a bunch of people thinking "Dampp- 
chaser systems cause pianos to be hot and unstable in pitch" or  
similar nonsense. There is a discrete reason for a particular set up  
to produce this result. I described it. It is unusual, I think.
	For my part, as I said earlier, I would not put a D/C system in a  
piano with a cover that is mostly impermeable to moisture, nor would I  
put such a cover on a D/C installed piano. What you do and how you  
deal with the situation is your business. If it causes you no pain,  
hey, no problem to me.
