STEP-BY-STEP WIRING AND ASSEMBLY DIRECTIONS
Be sure to carefully follow all the directions. Do one step at a time and then check off the step in the box provided.
Before beginning, read over the enclosed page labeled “Construction Hints”.
The step by step instructions indicate a soldering requirement; however, these connections can be made by firmly
twisting joining wires together. If the connection is secure the circuit will work for temporary or testing purposes. If
you wish a more permanent circuit, it is always best to secure these connections by soldering. Before soldering, read
the instructions in “Construction Hints”.
1. ( ) Check the parts list to see that everything listed
is included. Check each step as you progress (
).
2. ( ) Place the pictorial diagram near the perfboard
chassis so that the pictorial can be used as a guide for
exact placement of parts. The gray lines in the pictorial
diagram indicate components and wires which are
mounted under the circuit board. The solid lines
indicate components and wires mounted on top of the
circuit board.
3. ( ) Mount the transformer T1, as shown in the
drawing above. Install the transformer in the location
indicated in pictorial diagram.
4. ( ) Remove all of the insulation from a 1-
1/4”
piece
of wire. Solder one end to transformer T1 Pin 4 and
then solder the other end to transformer T1 Pin 5.
5. ( ) Insert the negative (-) and positive (+) battery
terminals into the perfboard positions indicated in the
pictorial diagram. If the battery terminals are loose in
the perfboard, apply a small blob of solder to keep
them from falling out.

6. ( ) Mount transistor Q1 as shown in the pictorial
diagram and compare with the diagram above. Note
that the pictorial is a top view and that a reversal of
leads takes place when you turn the transistor over to
solder leads to other components on the board.
7. ( ) Strip all insulation from a 1-
1/2” piece of wire.
Connect one end to the Collector (C) lead of transistor
Q1 and solder. Connect the other end to transformer
T1 Pin 3 and solder.
8. ( ) Insert the 15 Ohm resistor R7 into the perfboard
position indicated in the pictorial diagram. Connect one
lead to the negative (-) battery terminal and solder.
Connect the other end to the Emitter (E) lead of
transistor Q1 and solder.
9. ( ) Insert the 10K resistor R6 as shown in the
pictorial diagram. Connect one lead to transformer T1
Pin 4 and solder. Connect the other end to the Base
(B) lead of transistor Q1 and solder.
10. ( ) Insert the .47 MFD capacitor C7 as shown in
the pictorial diagram. Connect each lead to 10K
resistor R6 as shown and solder.
11. ( ) Insert the .22 MFD capacitor C6 as shown in
the pictorial diagram. Connect one lead to transformer
T1 Pin 6 and solder. Connect the other lead to .47
MFD capacitor C7 as shown and solder.
