Dear Richard, Finding the buzz is always the fun part !!! One item to check is bass string tails. Many of these pianos have no felt by the hitch pins and no stringing braid. You can discover a buzzing tail by plucking the tails. Fix it by installing stringing braid or just pry up the offending tail a little and insert a bit of felt between it and the plate. Good luck, Paul Hornberger,RPT
