I agree Jim. Like I said at the outset. There is no way a DC system is going to help significantly given these kinds of conditions. For crimminy sakes... theres a storm front in the room ! The pics are amazing. Really, this should be shown to health, fire and safety officials. Thats one heck of a lot of amperes buzzing away up there in that wet fog.... no way that can be safe. What kind of yahoo in charge doesnt see the major type mismalfunctionary problem and order a fix ? This goes way beyond whats good for the pianos me thinks. Cheers RicB I saw the data logger charts and the pictures. Conditions like that are unacceptable, and sometimes you just have to say so. Whether the HVAC system is old or new, if the relative humidity makes wild rapid swings and sometimes there is fog and condensate in the room, something is badly wrong and needs to be fixed. What is it doing now that cold weather is on the way? I wish you well in getting the point across to the right people. Jim Ellis
