On the subject of why Kimballs would be breaking strings, I might offer one possibility. On some pianos, usually of lower quality, ones that were carelessly strung, those that have had loose pins driven, poor design, etc. the string overlaps the coil as it comes off the pin, creating a sharp bend and weakening the wire at a point where there is a great deal of tension. This condition IMO, along with a severe angle around the plate bridge pins is why the Yamaha P-202s would throw strings like crazy in the bass section. Whether this condition applys to your situation or not, it pays to keep an eye out for these coils and tune the pin as gingerly as possible. Dave Bunch
