RAMSEY “LEARN-AS-YOU-BUILD” ASSEMBLY STRATEGY  

 

Be sure to read through all of the steps, and check the boxes as you go to be 

sure you didn't miss any important steps. Although you may be in a hurry to see 
results, before you switch on the power check all wiring and capacitors for 
proper orientation. Also check the board for any possible solder shorts, and/or 
cold solder joints. All of these mistakes could have detrimental effects on your 
kit - not to mention your ego! 
 

Kit building tips:   

Use a good soldering technique - let your soldering iron tip gently heat the 

traces to which you are soldering, heating both wires and pads simultaneously. 
Apply the solder on the iron and the pad when the pad is hot enough to melt the 
solder. The finished joint should look like a drop of water on paper, somewhat 
soaked in.   

Mount all electrical parts on the top side of  the board provided. The top side 

is clearly marked with the word “TOP”, you can’t miss it. This is the side that 
has little or no traces on it, but is covered with mostly copper. When parts are 
installed, the part is placed flat to the board, and the leads are bent on the 
backside of the board to prevent the part from falling out before soldering (1). 
The part is then soldered securely to the board (2-4), and the remaining lead 
length is then clipped off (5). Notice how the solder joint looks on close up, 
clean and smooth with no holes or sharp points (6).
