<HTML> <HEAD> <TITLE>Re: [CAUT] Killer half-octave</TITLE> </HEAD> <BODY> A super ball lost and wedged between the soundboard and plate certainly will make a killer octave, as will felt fuzz or dust bunnies on the strings at the front termination in that hidden recess under the pressure bar and dampers.  (dirty termination in the literal sense). -MJ On 5/16/07 1:07 PM, "David Love" <davidlovepianos@comcast.net> wrote: clean terminations would be well worth checking first.  Also, sample some other hammers in the section.  Heavily lacquered Steinway hammers have a way of developing TDD (tonal deficit disorder) and an inability to focus.   <BLOCKQUOTE> David Love davidlovepianos@comcast.net www.davidlovepianos.com -----Original Message----- From: caut-bounces@ptg.org [<a href="mailto:caut-bounces@ptg.org]">mailto:caut-bounces@ptg.org]</a> On Behalf Of Porritt, David Sent: Wednesday, May 16, 2007 5:48 AM To: College and University Technicians Subject: [CAUT] Killer half-octave Esteemed colleagues:   Our NY D, (1983) has developed – in the last year or so – a killer half-octave from about A#5 – E6. I’ve added some mass to the bridge right under C6 and that helped a little but the problem remains. I’ve been searching through the archives this morning checking for any further heroic measures I could take within the confines of my budget.     What’s the general consensus of opinion about the “Treble Tone Resonator” that Pianotek sells?  While my current budget precludes a full remanufacturing I think I can manage the $155.00 for that!  However, I don’t want to spend even that  – nor expend the time installing it  – if it wouldn’t help.     Any ideas, suggestions, experience with it etc.?????   dave   __________________________________ David M.
