<HTML><FONT FACE=arial,helvetica><FONT SIZE=2>Probably not the case if it's an entire section of hammers - but another

<BR><B>Subject:</B> sluggish upright jack
<BR>
<BR>
<BR>Hello,
<BR>
<BR> I had an old upright piano (Ludwig) with very sluggish jacks affecting
<BR>repetition particularly in the high trebel. Could this be from the coiled
<BR>jack spring? I lowered the capstan and eased the keys still didn't help
<BR>much. I noticed that there were no leads in the keys.
<BR>
<BR> Is this a sign that the wippen or the jack should be repinned? What
<BR>about treating with protek?
<BR>
<BR>Thanks for the help.
<BR>
