I ran into this with an SD10. You might have to loosen the strings from the section sufficiently to remove the metal plate(s) under which the strings run. The problem is often grooving of the plate(s). You must determine if it's one plate (older) or individual unison plates. My terminology is not correct, but I think you can follow. The one I did was 1975 & had one for each treble section. The treatment can actually be done in the piano, but you need to go by feel and use a light and mirror. I used Sanding tape which can be ordered from one of the piano supply houses or Constantine's in NY. Good luck. BTW, if it's an older one, Kent Webb informs me they don't make that replacement part any more. ?????
