Next we will wind L2. Use a small red toroid as your coil form, and repeat the procedure above,

but this time only put 32 turns on the coil. You will need to cut the wire to 18” to start. Don’t

forget to clean the insulation off the leads, it is very important. When it is finished set it aside.

Wind coil L3. Use a small red toroid, and cut your wire to 13”. Wind 22 Turns on the coil. Be

sure to clean the insulation off the leads.

Wind coil L4. Use a small red toroid and cut your wire to 11” . Wind 16 Turns on the coil. Be

sure to clean the insulation off the leads.

Wind coil L5. Use a small red toroid and cut your wire to 8”. Wind 11 Turns on the coil. Be sure

to clean the insulation off the leads.

Now we are ready to wind our last toroid. This will be a transformer, and is T1 on your parts list.

You will need two pieces of wire, one red one that is 16” long, and green one that is precut to 9”

for you. Start with the red wire. Wind 25 turns onto the all black toroid. Prepare the leads as

before. Now in you will wind the second part of the transformer. Use the green wire to put 5

turns on the core between the leads of the red wire as shown in Fig. 5. Be sure to prepare the

leads. Set the core aside for now.
