Now, use a small screwdriver (or just your finger on the plastic wheel) to
adjust trimmer R20 to the point where regeneration just begins, with all
other controls set as specified above. (This adjustment will be touched up
after the receiver is assembled into its cabinet.)
5-11. Take one last look at the quality of all solder connections!
Construction Phase 6 (Step 6-1 through 6-18)
Final Assembly
The receiver circuit board is designed for a precision fit into its custom aluminum
cabinet. To prevent both aggravation and possible damage, please follow our assembly
steps in order. Please do not install any parts ahead of time.
6-1. Arrange all remaining hardware parts so that you can look them and over and
visualize how they fit together.
6-2. Mount the two 4-40 screws and threaded spacers loosely in the two slotted
holes in the cabinet bottom. For now, keep the screw tips flush with the top
of the spacers.
6-3. Attach the four self-adhesive bumper feet to the bottom of the cabinet in a
symmetrical pattern.
6-4. Slip the PC board into the cabinet front-first, guiding the control shafts into
their respective panel holes. As you press the rear of the board down, pull
very gently on the rear panel to permit the phone jacks to slide into position.
6-5. As you settle the rear of the board, adjust the two screws and spacers to
match the PC board holes.
6-6. Gently bending the lead wires as needed, guide the LED bulb into its panel
hole. Use a small screwdriver blade or soldering tool to press the bulb
forward.
6-7. Use finger pressure to make sure that the two front panel controls and switch
are pressed forward against the front panel.
6-8. Attach the three panel washers and control mounting nuts (finger-tight only,
for now).
6-9. Tighten the two 4-40 mounting screws, treating the threaded spacers as nuts.
Install the self-locking nuts onto the screw lengths extending through the PC
board holes.
