Dampp-Chaser question

[Andrew and Rebeca Anderson]

Paul,
How high does humidity get there.  Assuming it gets to 70% and more 
here is a recipe I use that has tamed concert grands (no more than 2 
cents variation at any tuning, regulation still good an tight on the 
numbers a year later):
         Dual tank system with beeper (people don't replace the water 
unless it is annoying)
         38" rod just forward of the lyre to stabilize the keybed
         2 48"-50 rods down the sides of the piano with
         1 24"-25 rod going across up front
Full undercover and, if the piano is not going to be covered much, a 
full felt string-cover.

Placement of the humidistat is critical follow instructions exactly 
here for proper distance from the dehumidifier bars and the 
humidifiers.  Don't try to pull the cover tight but let it drape down 
so it doesn't touch any heater bars.  People do like the undercover 
as they don't like seeing the "balls" hanging under the piano on stage.
