STEP-BY-STEP ASSEMBLY
Before assembling your kit, please take time to read and understand the VEC kit
warranty printed on the inside cover of this manual. Also, read through the
assembly instructions to make sure the kit does not exceed your skill level.
Once
you begin construction, your kit will be non-returnable.
Finally, if you haven't
already done so, please verify that all parts listed in the inventory are included.
If anything is missing or broken, refer to the warranty instructions for
replacing missing or damaged parts.
Note that part designators. such as R1, C3, etc., appear on a silk-screened legend
on the component-mounting side of the printed circuit board. This corresponds
with the parts placement page in the manual. All parts will be inserted on the
silk-screen side of the board.
If you have last-minute questions about what you need to build your kit, please
refer back to the section titled "Tools and Supplies". If you're ready to begin
now. here we go! The directions use two sets of check boxes. Check one when a
step is complete and use the other for double-checking your work before
operation.
Important Note: Capacitors Cl-C8 are made of a polystyrene type material. Avoid
overheating these components when soldering to prevent melting the capacitor
body.
1. Locate capacitor C 1 (1000pF).
This is a polystyrene capacitor and
will be marked with a "1000P on the body (actual value in pF).
2. Mount C l and solder both leads in place, making sure the capacitor
remains seated, Remove excess leads on the bottom side of the board
with diagonal cutters.
3. Locate capacitor C2 (1000 pF). This is another polystyrene capacitor.
and it will be marked with a "1000J" (actual value in pF). Carefully
install C2 in the same manner as C1, and solder in place.
4. Locate capacitor C3 (1000pF). This is another polystyrene capacitor and
it will also be marked "1000T' (actual value in pF). Carefully install C3
in the same manner as C2, and solder in place.
5. Locate capacitor C4 (1000pF). This is another polystyrene capacitor and
will be marked "1000J" (actual value in pF). Carefully install C4 in the
same manner as C3, and solder in place.
6. Locate capacitor C5 (1000pF). This is yet another polystyrene capacitor
and will be marked "1000J" (actual value in pF). Carefully install C5
in the same manner as C4, and solder in place.
