After reading all the advice given to you on installing Dampp-Chaser's in this piano, I came back to your original post to
see what your original problem was. If I understand the above correctly, it is the center pins in the action that are
sluggish. Right?

If this is the case, Dampp-Chaser's will not help at all. Put as many as you like under the soundboard. They may well help to
stabilize the soundboard and the tuning. But, unless you put one in the action cavity just below the pinblock, they will have
no effect on the action center pins. And you should NEVER put a Dampp-Chaser under the pinblock. It will dry out the pinblock
and end up causing pin problems of another kind -- the tuning pins will become quite loose.
