                                                Original Rev. 2-APR-2008
                                                 Current Rev. 4-APR-2008


Please make  2  of these "Fuse Boards".  Each Fuse Board consists
of a  14" by 15"  1/4" thick  sheet of linen phenolic.


In this sheet there are  92  holes that are drilled and taped for
6-32 screws.  The X,Y location of these 92 holes is provided in
a table in this note.  I would be glad to put this X,Y information
into whatever format that would make it easy for you to cut and
paste it into you cnc mill.


Please feel free to suggest any design changes that would make
these parts easier for you to machine.


The purpose of these 2 fuse boards is to hold the individual power
fuses for each of the 30 preamp cards that are mounted in the
preamp box.

I have obtained all of the raw material that I believe is necessary
to make these brackets.  Please feel free to order anything else
that you need.
