Assembly Notes:
Please use thin silver-based solder (0.022" dia or less) and 15-20W fine point iron. You may mount
the resistors on either the top or bottom of the pcb. When mounting the sockets please make sure
that you align the socket 'fingers' with the pcb pads properly. For the unshielded plastic socket see
the note below. Melt a bit of solder on each of the pcb pads. Hold the socket in position and then
carefully apply heat to each of the socket fingers. if needed, apply a little solder to each. Double
check your work for solder bridges and splashes.
