                       Version 2.0


                 ///MATERIALS REQUIRED:///

1   - Radio Shack mini-box ( #270-235)
1   - 1/4 watt resistor, 2.2k-2.4k ohm (RS #271-1325)
1   - 75pf-100pf variable capacitor (Very hard to find)
2   - F61a chassis-type  coaxial connectors (RS #278-212)
12" - No. 12 solid copper wire
12" - RG59 coaxial cable


                      ///INSTRUCTIONS///

1.  Bare a length of No. 12 gauge solid copper wire and     twist
around a 3/8" nail or    rod to form a coil of 9  turns. Elongate
coil to a length of 1 1/2" inches and form   right angle bends on
each end.

2.  Solder the varible capacitor to the coil. It doesn't matter
where you solder it, it still does the same job.
The best place for it is in the center with the adjustment screw
facing upward 

Note: When it comes time to place coil in box,    the coil must
be insulated from grounding.  This can be    done by   crazy-
glueing   a piece   of rubber to the bottom of the box, and 
securing the coil to it. 

3.  Tap   coil at   points 2 1/2 turns from ends of    coil and
solder    to coaxial chassis  connectors, bringing tap leads
through   holes in chassis box.  Use as little wire as possible.

4.  Solder resistor to center of coil and ground other end of
resistor to chassis box, using solder lug and small
screw.

5.  Drill a 1/2" diameter hold in mini- box cover to permit
adjustment of the variable capacitor from    the outside.
Inspect   the device for defects in workmanship and    place
cover on minibox.  Tighten securely.

6.  Place device in line with existing cable on either side ofthe
coverter box and connect to television set with the short pieceof
RG59 coaxial   cable. Set television set to HBO channel.

7.  Using a plastic screwdriver    (non-metallic), adjust the
varible capacitor until picture tunes in.     Sit back,
relax, and enjoy!!!


Have fun...
