P7. Slip end B of wire #2 (see wire descriptions in Table 1 at
the end of this section) onto the top center lug (#2) of the
power sw itch.
P8. Slip end B of Wlre #3 onto the center lug of the fuseholder.
p9. Slip end A of wire #4 onto the side lug of the fuseholder.
PIIL Slip end B of Wlre #4 onto the bottom center lug (#5) of the
power switch.
Pll. Slip the
B
ends of wires #7 and #8 onto the two fan lugs.
The fan lugs may have to be bent slightly in order to slip
on the wires. Twist the wires together and leave the A ends
unattached for now. Check your assembly to this point with
figure lP for correctness. Set the back panel aside for
now.
P12. Mount the four adhesive-backed rubber feet onto the bottom
of the chassis frame, approximately 1" in towards the center
from each corner.
P13. Orient the chassis frame on the rubber feet so that the four
1/4" oval holes are on the right, away from you. The front
of the chassis is now closest to you.
P14. Mount the 180,000uf electrolytic capacitor as follows:
First attach a 6-32xl/2" tightening machine screw to the 3"
diameter capacitor clamp with a lock washer and nut. Next,
mount the clamp to the chassis frame in the location and
orientation as shown in figure 2P, using three 6-32x3/8"
machine screws and lock washers. Do not tighten the machine
screws yet. Next, insert the caoacitor into the clamp,
oriented as shown in figure 2P, forcing the bottom of the
capacitor to be flush with the frame. Finally, tighten the
clamp tightening machine screw and the three clamp mounting
machine screws.
PlS. Mount the stud diode mounting bracket in the location and
orientation shown in figure 2P, using two 6-32x3/8" machine
screws and lock washers.
P16. Mount end A of wire #13 and the stud diode with the longer
blue wire (#9) to the right hole of the stud diode mounting
bracket. The following order should result from back to
front: stud diode, mica washer, teflon ring, mounting
bracket, mica washer, #10 flat washer, end
A
of wire #13,
lock washer, and nut. Be sure the teflon ring is inside tne
bracket hole to insulate the diode from the bracket. Leave
end B of wire #13 and end
A
of wire #9 unattached for now.
P17. Similarly mount end
A
of wire #14 and the other stud diode
(wi th wire #10) to the left hole of the stud diode mounting
