Sostenuto headache

[Jon Page]

Look at the line of tabs, both straight -on and straight-down.
If a tab is higher than its neighbors - shim it.  Looking down through
the strings, if a tab is out further than its neighbors - push on  the
damper wire/ top flange to align the tabs.

Dampers regulated of course,
