Only fair sustain not as much power or woof to the sound. I've se=

<DIV><FONT face="Times New Roman" color=#000040 size=4> 3.=
Weak sound that breaks up & commonly shows particular impedance problem=
s in octave four & elsewhere. Loud or distorted attack or thwack as I ca=
ll it.(could be clang?) Can't be voiced out or to blend. Lots of old S&=
amp;S's especially L'S & O's</FONT></DIV>
<DIV><FONT face="Times New Roman" color=#000040 size=4> &nb=
sp; 4. Tends to sound choked for power but can still illicit some sustain wi=
th a harder /heavier hammer & careful voicing. Don't see this much</FONT=

<DIV><FONT face="Times New Roman" color=#000040 size=4> 5.=
Weakness in the offending area. I've induced this myself once in a S&S =
A-3 with new board. Repairing the bearing uniformity fixed the tonal pr=
oblem.</FONT></DIV>
