( ) 33 Kn (orange-orange-orange) 2 watt resis-
tor between lugs 3
(B-1)
and 18 (8-1).
( ) Place 5/8
t'
of sleeving on one lead of a 22 pf
mica capacitor and connect this lead to lug 3
of tube socket va (8-3). Connect the other
lead to lug 1 of terminal strip C (B-2).
( ) 680 KO (blue-gray-yellow) resistor between
lugs 4 (NS) and 19 (8-1).
( ) 1-1/2"
bare wire between lugs 5
(8-1)
and
20 (8-1).
( ) 1
megohm (brown-black-green) resistor be-
tween lugs
7 (8-1) and 22 (NS).
( ) 220 Kg (red-red-yellow) resistor between
lugs
6 (8-1)
and
21 (8-1).
( ) Connect
a
100 KQ (brown-black-yellow)
resistor from lug 1 of banana socket A (8-2)
to lug 2 of tube socket va (8-3).
( ) Connect
a .005
}.Lfd 500 V disc capacitor
between lug
5 (8-2)
and the center post
(N8)
of tube socket va.
( ) Connect a .005 Mfd 500 V disc capacitor be-
tween lug 6 (8-2) and the center post (8-6)
of tube socket va. Be sure lugs 1 and 4 are
soldered to the center post.
( ). Connect one end of a 3" white wire to lug 3
of tube socket V8 (N8). The other end will
be connected later.
( ) 150 KO (brown-green-yellow) resistor be-
tween lugs 8
(8-1)
and 23
(8-1).
Refer to Pictorial 4-3 for the following steps.
( ) .02 J.Lfd disc capacitor between lugs 1 (8-3)
and
4 (8-2).
( ) .02 /lfd
disc capacitor between lugs
1 (N8)
and 2 (8-1).
( ) 68
KO
(blue-gray-orange) 1 watt resistor
between lugs 12 (S-1) and 27 (8-1).
( ) 1000
n
(brown-black-red)
1
watt resistor
between lugs
10 (8-1)
and
25 (8-1).
( ) 8200 0
(gray-red-red) resistor between
lugs 9 (8-1) and 11 (8-1).
( ) 1-1/2" bare wire between lugs 14
(8-1)
and
29 (8-1).
( ) Pass one end of a 1-1/2" bare wirethrough
lug 31 (8-2) to lug 1 (NS). Connect the other
end to lug 16 (S-2).
( ) 47 Kg (yellow-violet-orange) resistor be-
tween lugs 15 (8-1) and 30 (8-1).
Connect the following parts to terminal board
#2.
( ) 15
Kg
(brown-green-orange) resistor be-
tween lugs 17 (S-1) and 22 (S-2).
( ) 100 KO (brown-black-yellow) resistor be-
tween lugs 16 (NS) and 24 (8-1).
Refer to Detail 4-3F for the following steps.
