Dampp Chaser and Grand Action

[Roger Wheelock]

Hi David,

Dampp-Chaser recommends keeping dehumidifiers out of the action.  This is
based on our experience and the concerns of piano manufacturers.

Dampp-Chaser developed a pin block dehumidifer a number of years ago.  The
challenge was two rather large holes had to be drilled to gain access to the
action.  Members of our local PTG chapter took a look and explained that no
technician would want to drill those holes.

We are open to any ideas you folks might have.  Feel free to email me off
the list.

Roger
