Carl, Is your reference to "wonderful instrument" tongue in cheek? :-) My impression is that most techs wouldn't refer to *any* square grand as a wonderful instrument. They're pretty, though. I can't make any further observations about square grands, since I never worked on one and never intend to. As far as the CA treatment goes, my results with it have been so-so. It usually seems to do some good, but not always, and sometimes not very much. But I might be too cautious in how much I use, because I don't want to overdo it. I used a whole bottle on an old upright once, and they got way too tight. But I talked with another guy who used two bottles (2 oz.) on a piano before he noticed any improvement. Did you try tapping the pins a little deeper, if there's enough room on the pins below the coils to do that? Be sure to brace the pinblock, of course. I suggest that because I did that once on a 1974 Kawai grand. I tried tapping a few of the loose pins, just enough to see some movement downwards, and they felt like a new piano! So I did them all. But your piano has a much worse case of loose pins than this one did.
