Shaper Boards

Hall D Electronics:

Dear Gerard 

   as Yves mentions late last week, several of the channels 
on the shaper board that we have here appear to not work.
The noise is signifcantly larger than the other channels. You
had mentioned that this might be an issue with the differential
receiver part of the board. 

    Is there a simple fix that we can do here for this, or can you 
send us a board where all the channels work? If it does come 
to sending us a board, getting it here quickly would be very good.

  thanks in advance - Curtis
