Modifications to Extron ADA 6 Component for use as a 50 , 1/5/10 MHz distribution amplifier:

1.   Replace 3x 75  input resistors with 50  resistors (SMD 1206).
         On the ADA 6 Component PC board, these are R37-R39.
     NOTE: one may want to parallel two or all three inputs internally to give a 1x12 plus 1x6 or a 1x18
     configuration. In that case, use only as many 50  resistors as there are separate inputs. Removing the
     unused input BNC connectors may avoid future mishaps. Fill the empty rear panel holes with hole plugs.
     NOTE ALSO: To use the modified unit to buffer the output of an oscillator that is not rated to drive 50 ,
     such as the HP 10811 or 10544, other values of input termination can be used -- 1k  in the case of the
     10811/10544, which would require 1.111k  terminating resistors (taking into account the existing 10k 
     input bias return resistors, which are in parallel).

2.   Replace 3x 100
