Since you did not ask me I would say the DC would not help that problem. After it becomes stabilized at A-440, probably so. One does not undo many years of lack of service and quickly it becomes OK.

My question is more related to the fact, that the piano had never been tuned in its previous life and it stabilized off pitch and out of tune. Would a climate control system compensate and stabilize this kind of a piano enough to warrant its expense? -Ursula Ursula Hammerling Registered Piano Technician Washington, NJ 07882 =================== --- On Tue, 5/4/10, Qshooterq at aol.com <Qshooterq at aol.com> wrote: From: Qshooterq at aol.com <Qshooterq at aol.com> Subject: Re: [pianotech] Question with Climate Control System To: pianotech at ptg.org Date: Tuesday, May 4, 2010, 5:57 PM Hi, Ursula, If the are no visible signs of damage then that's the place to start. I have a related story. I had trouble with a 7ft Bosendorfer with wild swings from tuning to tuning. The customer said that humidity swings were not an issue in his house. I installed a dehumdifier. The problem improved by 50%. Shortly afterward they moved. At the new location the piano was as solid as a rock. The moral of the story -- don't believe the customer, use Dampp Chaser's meter that records the high and low humidity. ---Tom Gorley In a message dated 5/4/10 11:27:02 AM, ursulapianotuning at yahoo.com writes: Hi List, I have a customer with a 40 year old Baldwin spinet. When she acquired it, the owner told her, it had never been tuned. This piano is very unstable on 2 tunings a year. Does any one of you have experience with a climate control system in this kind of a case. I put climate control systems into other pianos with good results, but am not quite sure, whether it is justified in such a case, whether the tuning would become much more stable. Is this throwing good money after a hopeless piano? Thanks, Ursula
