Install the Not so Tall Polarized Capacitors 
It’s important to install these caps with the proper polarity. The negative end of the cap is 
marked with a minus sign. The silk screen on the board marks where the positive end of 
the cap goes. Make sure that the negative end of the cap is away from the plus sign on the 
circuit board. 
Install the Fuse and Fuse Holder 
Solder the body of the fuse holder shown on the left side of Figure 3 into 
screen marked F1 on the PCB. 
 
Insert the 0.25 Amp (for 120-Volt operation) or the 0.125 Amp (for 240-
Volt operation) fuse into the fuse holder lid.
 
Fit the combination of the fuse plus the fuse-holder lid into the body to 
complete fuse installation.
