In the following steps, you will mount
eight brass tubes on the circuit board. So
they will take the solder easily, 1/4" of
the end of each tube should be burnished
with steel wool or fine sandpaper until it is
bright. To mount the tubes, push them
through the top of the board until they
project approximately 1/32" through the
foil side. Space the top of the tubes with
the indicated small boards; then solder the
tubes to the large circuit board foil. Solder
around the circumference of each tube.
Remove the small board from the top of
the tubes temporarily.
