Eliminating the tuned duplex by either substituting a continuous counter bearing for the individual aliquots, or moving the individual aliquots to a nominally straight line with the shortest practical duplex length would take care of the duplex tuning issues. A strip of butt felt of a height just barely higher then the counter bearing bar(s) would mute the section without adding a significant amount of friction from the felt. Not felting behind the counter bearing lets the segment between the counter bearing and the tuning pin speak, which may not prove to be optimal. It's not any more complicated than that. Ron N
