8. Install a 470 pF at C27 and solder.
!
!
9. Install a 470 pF at C28 and solder.
!
!
10. Find the 1000 pF (or .001 uF) multilayer capacitor (102). Install at
C24 and solder.
Find three (3) 4.7 uH molded chokes (yellow-violet-gold, silver or gold)
!
!
11. Install a 4.7 uH at L1 and solder.
!
!
12. Install a 4.7 uH at L2 and solder.
!
!
13. Install a 4.7 uH at L3 and solder.
Locate two T50-2 toroid coil forms (½" donut-shaped form, red color code).
Also, find the #24 enameled coil wire provided with your kit.
!
!
14. Wind thirty (30) turns of #24 enameled wire onto the T50-2 form.
Note that turns are counted
inside
the form, and each turn is pulled
tight before winding the next. Spread the windings out, distributing
over 80% of the form's circumference.
!
!
15. Trim each coil lead to ½" in length and tin with solder.
!
!
16. Wind a two-turn secondary link of hook-up wire over the center
portion of the primary winding (two turns passing through the center).
Install at T1, laying flat--as shown below. Save unused portion of
insulated wire--you will need 4" of insulated wire later.

17. Solder T1 in place.
Find the #22 wire.
!
!
18. Wind 16 turns of #22 enameled wire on a T50-2 toroid form. Spread
windings for 80% coverage, and install at L4 in an upright position.
