[pianotech] String Breakage

[Richard]

Along those lines, Steinway "45" only 3yrs old and as of last week  
three 17 gauge strings have broken during pitch corrections of not  
more than 5-7 cents.
First one broke at first tuning, next one a year later. What's the  
deal? Used clp and lowered string before raising pitch.
