Sound coming from the plate

Corte,
         I certainly have and have attributed it to the rail that limits 
damper lever travel. A definite "BONG" sound. Big pain in the butt while 
tuning that you almost can't hear with the case parts back on. That part is 
normally a hammer spring rail but in this case the springs are on the 
hammer butts. Hope this helps.
