The board is blackened some but may be ok.  I figured it might be easier 
to swap the board out versus me trying to replace the resistors.  I 
looked in the 520S service manual and it shows 7 resistors on the final 
board.  I have 8 for some reason.  I'm thinking this board might have 
had some work done previously.  I'm in the process of studying the 
schematic from the service manual to try to figure this out.
