( ) Cut one lead of a 200 pf mica capacitor to
1/4". Connect this lead to solder lug
M
(8-1).
The other lead will be connected later.
( ) Connect one end of a 3-1 /2" red stranded
wire to lug 3 of variable capacitor TC (8-1).
The other
end will be connected later.
( ) Connect a .005 /lfd 500 V disc capacitor
between lugs 6 (NS) and 11 (NS) of tube
socket V11. Position this capacitor as close
as possible to tube socket Vl1 to prevent it
from interfering
with a shield that is in-
stalled later.
( ) Connect a 10
n
(brown-black-black)
re-
sistor between lugs 4 (NS) and 10 (8-3) of
tube socket VII.
( ) Connect one end of a 2-1/2" red stranded
wire to the stranded wire connected be-
tween lugs I and 2 of variable capacitor
TC (8-1). The other end will be connected
later.
( ) Connect a .005 /.lfd 500 V disc capacitor
between lugs 4 (NS) and 10 (NS) of tube
socket V11.
( ) Remove I" of insulation from one end and
1/4" of insulation from the other end of a 2"
red stranded wire. Connect the end with the
most insulation removed around lug 2 (8-2)
to lug 1 (S-I) of variable capacitor TC. The
other end will be connected later.
( ) Connect a .005 /lfd 500 V disc capacitor
between lugs 3 (NS)and 10 (NS)of tube sock-
et Vll.
( ) Connect one end of a 1-1 /2" white wire to
lug
2
of terminal
strip
N
(8-2). The other
end of this wire will be connected later.
'
( ) Connect a 10
n
(brown-black-black) resistor
between lugs 1 (8-2) and 9 (8-3) of tube sock-
et VII.
( ) Connect a .01
/-lfd
disc capacitor between
lugs 2(NS) and 3 (N8) of terminal strip
N.
( ) Pass oneleadofa.005/lfd500V
disc capac-
itor through lug
9
(N8) to lug
2
(8-1) of tube
socket V11. Connect the other lead to lug 1 of
tube socket V11 (N8).
( ) Connect a 1" length of large bare wire be-
tween lugs 8 (8-1)andI2 (S-2) of tube socket
VIO. Cut off the excess wire.
( ) Connect a 2_3
/4" red stranded wire from
lug
7
of tube socket VIa (8-3) to lug
7
of
tube socket V11 (8-2).
( ) Connect a .005 Jlfd 500 V disc capacitor
between lugs 7 (NS) and 12 (NS) of tube
socket VIO.
( ) Connect a 2" red stranded wire from lug 5 of
terminal strip R (NS) to lug 7 of tube sock-
et V10
(NS).
( ) Connect a 10
n
(brown-black-black)
resis-
tor between lugs 6 (8-2) and 11 (8-3) of tube
socket VIO.
( ) Connect
a
T' large bare wire between lugs
8 (8-1) and 12 (8-2) of tube socket VII. Cut
off the
excess
wire.
( ) Connect a .005 Mfd 500
V
disc capacitor
between lugs 6 (N8) and 11 (N8) of tube
socket
V1D.
( ) Connect a .005
ufd
500 V disc capacitor be-
tween lugs
7
(N8) and 12 (NS) of tube socket
V1l.
( ) Connect a .005 Ilfd 500 V disc capacitor
from lug
5
of terminal strip
R
(NS) to lug
11 of tube socket VI0 (NS).
( ) Connect a 10
n
(brown-black-black)
re-
sistor
between lugs
6
(8-2) and 11 (8-2)
of tube socket V11.
( ) Connect
a
10
n
(brown-black-black)
re-
sistor between lugs
4
(N8) and 10 (S-3) of
tube socket V10.
