( X) Cut the other resistor lead to 3 /8"' and connect to socket pin 3 (S). Keep the resistor close
to the tube socket.
(X) Cut one lead of a 2.2 megohm resistor (red-red-green) to 5/8" and the other lead to 1/2".
Bend the leads as shown in Pictorial 1. Connect the 5/8" lead to ground lug 2 (S) and the
1/2" lead to pin 2 (NS).
(4) Cut both leads of a 2.2 megohm resistor to 1/2" and connect from ground lug 3 (S) to pin 7
(NS).
Mount the 100 wyf tuning capacitor near the top front of the chassis in the following man-
ner. First bend the capacitor terminals at right angles as shown in Figure 2. Insert four
4-40 x 3/8" screws through the 1/8" holes and place 3/16" s; acers over them. Place the
capacitor over the screws, and holding the screws with the fingers and the capacitor with
the thumb of one hand, start each screw separately. When ail screws are started, align
the capacitor squarely and tighten all screws.

(x) Mount the two 4-lug terminal strips in the positions shown in Figure 2, using 6-32 screws,
lockwashers and nuts. ,
(x) Mount a 5/16" and a 3/8" grommet on the rear chassis apron as shown.
(<) Bend a solder lug at right angles 3/8"'from the narrow endand mount it between the grom-
mets. Do not use a lockwasher here.
NOTE: In order to show the wiring on the pictorial drawing, the «oil terminals are not illus-
trated in their exact position. The terminals of both coils should face directly toward the front
and rear of the chassis and parallel to the sides. Either terminal may be toward the rear.
(X) Mount the 1.5-3.0 mh coil #40-67 (this is the coil not completely enclosed by an external
core) in the 5/16" hole nearest the top of the chassis and terminal strip A. See Figure 2.
(<) Connect a .005 uid disc ceramic capacitor from A2 (NS) to coil terminal 2 (S).
(<) Connect a .005 pfd capacitor from A2 (NS) to A3 (NS). See Pictorial 1 and keep the capaci-
tor close to the terminal strip to allow room for the two mica "apacitors.
(x) Connect a .005 ufd capacitor from Al (NS) to terminal 1 of the coil (NS).
(X) Connect a wire to Al (S). Leave the wire long enoughto reach pin 1 of the tube socket (about
2 1/2"). Strip the end but do not connect yet.
(X) Cut a wire to 3 3/4", strip both ends and connect one end to terminal 1 of the coil (NS).
Leave the other end free.
(X) Cut one lead of a .005 fd capacitor to 1/2" and connect to terminal 1 of the coil (S).
(X) Slip a 1 1/8" length of sleeving over the other lead and connect to A4 (NS).
(X) Connect a 10 KQ resistor (brown-black-orange) from A3. (NS) to Bl (NS).
(X) Mount the 120-150 wh Q multiplier coil in the 5/16" hole between the tube socket and chas-
sis rear, arranging the lugs as referred to in the note above.
( Slip a bare wire through the #1 coil terminal (NS) and connect to the lower tuning capacitor
terminal (S). See Pictorial 1. .
