CLIP-ON COIN CADDY
W
olf Industries has just announced
a new coin/token dispenser(patent
pending). This handy "COIN CADDY'' stores
up to $5 in quarters or 20 tokens. The built-on
clip makes it easy to clip onto a belt, shirt
pocket or auto sunvisor. The inner spring
holds coins securely even when the COIN
CADDY is upside down. It produces one-
handed change fast. It's ideal for arcade
game enthusiasts, vending machine fre-
quenters and do-it-yourself car washers. It is
also convenient for laundramats, toll gates,
pay phones, jukeboxes and even slot machines.
The COi N CADDY will be marketed as a high
profit, fast moving impulse item that anyone
can afford. The product retails for under two
dollars and has a high profit margin for retailers
and distributors. Individual packaging and
displays are available as merchandising aids.
The COIN CADDYmaybepersonalizedwitha
special message or graphics which makes it a
unique and useful promotional item. The COIN
CADDY is available in standard colors of
yellow, white and black. Special colors may
also be ordered. Wolf Industries is currently
seeking distribution to retail outlets and
promotional marketers. For more information,

DEFLECTION PCB
v.
ou should do the following modifica-
ion to help prevent the Deflection
PCB from failing. This modification should
only be performed by a qualified technician.
1. Connect the two type-1 N754A zener
diodes together as shown in Figure 1. The
connection is made as follows: bend the
anode ends of both diodes into a "fish
hook" pattern. Hook the two fish-hooked
leads together, and solder them. Remem-
ber that too much heat will destroy the
semiconductor material.
2. Connect the two type-1 N756A zener
diodes together as shown in Figure 1. Use
the same technique as described in Step
1 above.
3. Remove diode CR2 and solder in a type-
1 N4002 diode in its place.
4. Remove diode CR 11 and solder in a type-
1 N4002 diode in its place.
5. Remove resistor R12 and solder in a
12 n , ¼W resistor in its place.

6. Remove resistor R35 and solder in a
12.n., ¼W resistor in its place.
7. Find the Y-Deflection Circuit (upper left
area of the schematic). Resistor R1 has
two leads to it. Find the lead that goes to
the yellow wire. Connect this lead to the
cathodeofoneofthetype-1 N754Adiodes.
Connect the cathode of the other type-
1 N754A diode to ground.
8. Find resistor R24. It has two leads: one
runs to an orange wire. Connect this lead
to the cathode of one of the type-1 N756A
diodes. Connect the cathode of the other
type-1 N756A diode to ground.
9. Find the type-2N3792 transistor Q17.
You will be installing a type-1 N4002 diode
across this transistor's emitter and col-
lector. Solder the cathode lead of the
type-1 N4002 diode to the emitter, and
solder the anode to the collector of this
transistor.
10. Find the type-2 N3617 transistor desig•
nated 016. You will be installing a type-
1 N4002 diode across this transistor's
em itter and collector. Solder the cathode
lead of the type-1 N4002 diode to the
collector, and solder the anode to the
emitter of this transistor.
11. Find the type-2N3792 transistor Q7. You
will be installing a type-1 N4002 diode
across this transistor's emitter and collec-
tor. Solder the cathode lead of the type-
1 N4002 diode to the emitter, and solder
the anode to the collector of this transistor.
12. Find the type-2N3716 transistor Q6. You
will be installing a type-1 N4002 diode
across this transistor's emitter and col-
lector. Solder the cathode lead of the
type-1 N4002 diode to the collector, and
solder the anode to the emitter of this
transistor.
