What's to know? Tuned front duplexes have been repeatedly 
demonstrated to be a less than sterling idea for a long time 
because of their tendency to be noisy. The fix is to eliminate 
that patent feature, and replace it with a continuous counter 
bearing bar leaving the front duplexes as short as possible. 
The patch is most effectively to apply "Pitchlock" couplers to 
the duplex lengths. At least that's my call.
