<DIV><STRONG><FONT face=Arial>Sounds like jerky pins. =
</FONT></STRONG></DIV>
<DIV><STRONG><FONT face=Arial>Young Chang had a problem with the same =
symptoms,
and it was a contaminated pinblock.</FONT></STRONG></DIV>
<DIV><STRONG><FONT face=Arial>In their case it had been caused by a =
silicone
lubricant used at the factory to ease the driving of the plate securing
screws.</FONT></STRONG></DIV>
<DIV><STRONG><FONT face=Arial>Someone hasn't used WD40, to make sure =
the strings
and pins won't rust?</FONT></STRONG></DIV>
<DIV><STRONG><FONT face=Arial>Or is it a rust bond that has formed =
where the
string contacts the plates, due to raising the humidity. That sounds =
more like a
ping, though, and it would show up, whether raising or lowering the
pitch.</FONT></STRONG></DIV>
