In the following steps you will install parts in the cabinet
bottom.
Refer to Detail 4-1A and mount an SPST switch with
spring return at C. Use two 6-32 x 3/8" flat head
screws and a #6 solder lug. Be sure the switch lugs and
solder lug are positioned as shown.
In a similar manner
,
mount another #6 solder lug and
SPST switch with spring return at D.
Mount a DPDT switch and a #6 solder lug at E. Use
two 6-32 x 3/8" flat head screws.
( NI) Mount a DPDT switch and a #6 solder lug at F. Use
two 6-32 x 3/8" flat head screws.
(Nr Install switch insulators on switches C, D, E, and F;
and bend the lugs to 45
°
as shown.
) Prepare a 5" length of black wire by removing 3" of
insulation from one end and 1/4" of insulation from
the other end.
Insert the 3" bared end through the top hole of each
of the four solder lugs, starting with the solder lug at
C.
-
Iv.) Solder this wire to solder lug F, and then to the three
other lugs. The other end of the wire will be
connected later; route it as shown.
Refer to Detail 4-1B and install the speaker as shown.
Use two speaker clamps and two 2-32 x 1/4"
self-tapping screws. Do not overtighten the screws.
Remove the protective backing from the 1" x 1"
piece
of fish paper. Center this paper over the back of the
speaker and press the adhesive side against the speaker
as shown in Detail 4-1B.
Refer to Detail 4-1C and mount the transformer. Be
sure the wires are as shown. Use a 6-32 x 3/8" black
screw, a #6 flat washer, a #6 lockwasher, and a 6-32
nut at G. Use a 6-32 x 3/8" black screw, a #6 flat
washer, two
#6
lockwashers, a terminal stirp, and a
6-32 nut at H.
