Resistor, RFC and Diode placement

Caution: The 1N4148 and 1N5231 diodes look identical, read the numbers carefully on the side of the part. A magnifying glass 
maybe required. Observe polarity as indicated by black line on one end of the part and diagram. 

Sorting the resistors into their various values before hand will speed up assembly. 

 Install all the resistors of one value at a time. The location/value table is set up for this.  

 Parts are numbered on the board from left to right, top to bottom in diagonal rows.
