<html> <body> Brett, Pull on the cross strut while producing that buzzing sound.  If it ameliorates: back-out the screw a little then tighten it (Bill Youse recommends giving the strut a tap with a rubber mallet to seat it) both ends.  This is not that uncommon, it can loosen up if the piano is moved a lot.  I ended up trickling CA glue around one here to eliminate the buzzing because the screws wouldn't budge either way.

When I first got the contract to tune for them I was excited . Now I don't look forward to it . The 5th & 6th octaves have this harsh buzzing sound . Is that what you mean by killer octave ? I even thought that something was loose on the soundboard, nothing found. I called the Tech that went to New York to pick it out for them and asked him . He thought that it is OK no problem. And says concert performers like a piano like that . I don't think so. Although it does sound better when your setting in the auditorium .   I had the pleasure of replacing an Agraffe & tuning  a 1925 B yesterday . This piano was great. The best Steinway I've ever played. The 5th & 6th octaves were clear as a bell excellent. Some Tech in CA did a fantastic job. I only hope to do work that good. By the way the agraffe came right out through the bottom of the plate. Thank god. I was ready for a fight .   Brett -- <a href="http://a8-asy.a8ww.net/a8-ads/adred?redirectid=mailfamily_a_target01"> <img src="http://a8-asy.a8ww.net/a8-ads/adred?redirectid=mailfamily_img_src01" alt="[]"> </a> </blockquote></body> </html>
