In addition to the above pieces of hardware, you should still have a thin steel flat

washer, a 3/8" hex nut and the screws for the slide switch wired to the circuit

board. These parts were left from the VEC-820K kit. You were asked not to

discard them, because they will be needed for installing the circuit board in an

enclosure. If possible, you need to locate them.

STEP-BY-STEP ASSEMBLY

To install your receiver in the VEC-830KC matching enclosure follow these

instructions (read all instructions before beginning ... take your time) :

Installing the Circuit Board

Please refer to the Parts Placement diagram for hardware locations.

¢ ¢ 1. Find the front panel decal that corresponds with your receiver and the

rear panel decal; separate using scissors. Be sure to leave excess decal

material around the edges. Put the rear panel decal on first. This is

done by: a.) Remove all debris and oil from the chassis. This should

be done using a piece of cloth and alcohol. b.) Remove the crack and

peel to expose the adhesive. c.) Place the decal on the rear panel

without securing it completely. d.) Gently rub the alignment circles

and/or rectangles with your finger--if the circles and/or rectangles are

centered in the enclosure holes (also check the corner alignment

marks) secure the decal by rubbing and removing all air bubbles. e.) If

the alignment circles and/or rectangles are not centered, adjust the

decal accordingly then secure. f.) Use a penknife, or small Exacto TM

knife, to cut away the unused edges (cut from the adhesive side) and

cut out the component holes (cut from the description side). g.)

Repeat procedure for the front panel.

¢ ¢ 2. Desolder and remove the RED battery snap lead from the VCC point

on the circuit board. Make sure the hole where the RED battery snap

wire was is completely clear of solder.

¢ ¢ 3. Insert one end of a 1 1/2" insulated wire into the hole at the Point

labeled VCC on the circuit board. Solder in place and trim the excess

lead.

¢ ¢ 4. Place the bottom chassis in front of you with the round hole in the

front panel facing you.

¢ ¢ 5. Install the two L-brackets on the chassis using two of the 4-40 x 3/16"

machine screws (1). The longer side of the L-bracket must be

connected to the chassis using the two holes centered on each edge of

the enclosure. Refer to the Parts Placement diagram for the location

and orientation.

¢ ¢ 6. Mount the circuit board in the chassis. Remember, the large slide

switch already wired to the board goes into the slot next to the round

hole in the front panel. Mount the board a follows: a.) Insert the 4-40

x 1/2" machine screws (2) into the holes in the chassis, then sit the

chassis on the table so the screws do not fall out. b.) Slip one #4 x

3/16" spacer ( 7 ) over each screw. c.) Sit the board down onto the

screws, making sure the knob on the large slide switch is inserted into

it's slot. d.) Install the angled solder lug on the screw at the left rear

corner of the board. e.) Secure the board to the screws using four 4-40

hex nuts (3) and tighten.

¢ ¢ 7. Secure the large slide switch (SW1) using two 4-40 x 3/16" machine

screws (1) that came with the VEC-830K kit. Tighten the screws in

place.

¢ ¢ 8. Install the small slide switch (SW2) to the rear panel using two 2-56 x

3/16" black machine screws (4) and two 2-56 hex nuts ( 5 ). Orient the

switch so the black knob is extending out of the rear panel.

¢ ¢ 9. Install the 1/4" mono phone jack (11) as follows: a.) Slip the flat steel

washer (15) over the threaded end of the jack. b.) Install the threaded

end of the jack from the inside of the chassis through the front panel

hole. c.) Position the jack as shown in the Parts Placement diagram.

d.) Secure the jack to the front panel using the 9MM hex nut (12).

¢ ¢ 10. Install the screw-type terminal board (10) into the horizontal slot on

the rear panel using two 4-40 x 3/16" machine screws (1) and two (2)

4-40 hex nuts (3). Install the terminal board on the inside of the

chassis.

Wiring the Enclosure

You must position the enclosure so the front panel is facing you. For the

following point-to-point wiring steps you will also require the VEC-820K

manual to locate some of the reference points mentioned.

¢ ¢ 1. Connect the insulated wire, located at the point labeled INPUT on the

circuit board, to the right solder lug on the terminal board. The right

lug is the one closest to SW2. Solder in place.

¢ ¢ 2. Find a 3" piece of insulated wire. Cut a piece 1½" long and remove

¼" of the insulation from each end of the 1½" piece.

¢ ¢ 3. Connect the 1½" insulated wire between the left most lug on the

terminal board and the angled solder lug located on the board. Solder

both ends of the wire in place.

¢ ¢ 4. Find another 3" piece of insulated wire. Cut a piece 2½" long and

remove ¼" of the insulation from each end of the 2½" piece.
