Digital BW, The Print

I concur with Greg. You don't want dry jets.  

Also, you'll probably need a ribbon with 6 tubes anyway.  These 
ribbons flop all over the place if too narrow.  Getting one of these 
that is appropriate will be one of the challenges.  I'm not sure what 
the best source is.

You'll also probably need some way to transition between the damper 
and the inlet size as well as the incoming tubing.  The dampers I 
have for the 7500 use a smaller tube. 

Let us know how the project works out.
