Dear esteemed colleagues: I am tuning a 1968 Baldwin D grand (9') today and am having quite a bit of trouble with string rendering in the two treble sections. This piano has the unusual treble forward terminations that Baldwin has used (pictured below) - I have heard of them before, but this is the first one I've actually run across. I will be going back to the piano later this afternoon to finish. I will be trying some Protek on the two forward termination bars. String rendering on the treble of this piano is very unusual. The treble was a bit flat. First I nudge the tuning pin to turn and bring the pitch up just a cent or two above target pitch. Then when I go to nudge the pin to lower pitch to target, as I put pressure on the tuning lever to lower pitch the pitch will actually rise about five cents before it starts going down. Same thing if the pitch is a couple cents sharp - lower pitch just below target and when you apply pressure to raise pitch to target, the pitch actually drops five or so cents more flat before rising. And then of course, after you think you have the pitch where you want it and the pin is settled in a neutral position, the pitch goes five or more cents sharp or flat. This is not your typical Yamaha C3! Does anyone have any other tips or tricks to offer a slightly frustrated piano technician? Anyone knowledgable on the evolution of large Baldwin grands? Where does the model D fit in? Is it a precursor to the SD-10? Major differences? I see this one has a fairly large straight upper bass soundboard cut-off bar. Seems like a nice piano. Thanks!
