Or, do you think I should forget about humidity control and just get in there and fix the problem >> Clyde: I have noticed the problem on Steinways is much of the time a problem with action centers getting overrun with vertigris- a green chemical reaction which attacks these center pins. The problem is amplified due to high humidity, I am sure, and is more noticeable in the treble because she probably doesn't play there as much as the rest of the keyboard. Use Protek on the center pins and "flex" them individually until you notice improved movement. Some Techs feel this is attacking the problem and the problem will return. I agree, but find this is a 4-5 year solution. As far as DC system: if humidity is always a problem, and she seldom uses air conditioning, I would install just the de-humidifiers but include a humidistat. Donot, under any circumstances make this installation without this control. Bob Bergantino, RPT Willoughby Hills, Ohio
