be used.
! Place the capacitor at its mounting location at the center front of the board.
The body of the capacitor should sit about 1/8” back from the board edge.
Use a ruler to center the capacitor body at 3” from either outside board
edge.
! Mark the capacitor body outline by tracing its outline onto the breadboard
with a pencil.
! Find the double-sided foam tape.
! Remove one of the protective covers from one side of the tape. Place the
sticky side over the capacitor outline on the breadboard. Firmly press the
tape to set the adhesive.
! Remove the protective cover over the top of the tape.
! While being careful to keep the capacitor centered on the board, and parallel
to the front edge of the board, press it to the foam tape. Apply gentle, but
firm, pressure to set the adhesive.
! Find the ¼” diameter aluminum tuning shaft extension. Align the threaded
screw end with the opening in the capacitor tuning shaft. Screw the
extension into the tuning capacitor.
! Unscrew the tuning shaft about 1 or 2 turns, to open a gap between the two
shafts.
