<html> <body> Mr. Maret, You will find Mrs. Acker to be a competent source of information on this question.  You can reach her via email at:  a.acker@comcast.net Regards, Andrew Anderson At 01:38 PM 9/21/2007, you wrote: <blockquote type=cite class=cite cite="">A local church has a Zuckerman, Double Choir Harpsichord.  I don't know if this was a kit or not, but the coils on the pins are not very neat, so I suspect it's a kit.  When I tune it to A-440, strings break.  I've currently tuned it to A-415 (one semi-tone flat), but the music director isn't happy transposing everything.  I'm betting the bridge is in the wrong place, causing the string tension to reach the breaking point at A-440.  I'd be interested in any suggestions on a cost-effective fix.    Bob Maret, RPT Piano Technician <hr> See what's new at <a href="http://www.aol.com?NCID=AOLCMP00300000001170">AOL.com</a> and <a href="http://www.aol.com/mksplash.adp?NCID=AOLCMP00300000001169">Make AOL Your Homepage</a>.</blockquote></body> </html>
