rating of cupmitors is obtained by multiplying the color value
by 100. For example: orange = 3 X 100 or 300 volts Blue
6 X 100 or 600 volts.

Connect a 4 3/4" length of wire between E1 (NS) and D1 (NS).

Connect one end of an 8" length of wire to K1 (NS). Run this wire between terminalslrip J
and socket F and connect to E3 (NS). Dress this wire close to chassis.

Connect a 1500 n resistor (brown-green-red) between J2 (NS) and E8 (NS).
Connect a 10 of tubular electrolytic capacitor between C3 (NS) and E8 (S). IMPORTANT:
Be sure the positive (+) end of this capacitor connects to E8. Before soldering, rotate this

capacitor so that the positive lead goes straight to E8 and avoids E7.

Connect a 100 K 5% resistor (brown-black-yeHow-gold) between C3 (S) and E7 (NS). Let
the resistor rest lightly against the 10 of electrolytic capacitor.

Connect another 10 of tubular electrolytic capacitor between G2 (NS) and D8 (NS). Observe
polarity as before with the positive (+) lead going to D8.

Connect a 1500 n resistor (brown-grezn-red) between G2 (NS) and D8 (S).

Connect a 100 K 5% resistor (brown-black-yellow-gold) between G1 (NS) and D7 (NS).
Install a 10 K 5% resistor (brown-black-orange-gold) between G2 (S) and G1 (NS).

Connect a 150 K 5% resistor (brown-greensyellowvgold) between G1 (NS) and ADI (NS).
Connect a 100 K 5% resistor (brown-blackeyellow-gold) between GI (S) and M2 (S) (use
sleeving on the end going to M2).

Install a 4700 Q resistor (yellow-violet-red) between CA (S) and CI (S). Note the position
of this resistor in the pictorial.

Install a 100 K 5% resistor (brown-black-yellow-gold) between D1 (S) and D6 (NS).

Install a 100 K 5% resistor between E1 (S) and E6 (NS).

Slip a 1 3/8" length of insulated sleeving on each lead of a .1 of capacitor and connect the
capacitor between ADl (S) and D3 (NS). Dress this capacitor close to the chassis end plate.
WflhmzflmWW-M. Note: Do not use capacitor marked
"5%"heré. " '

Connect a 1 1/2" length of wire from AC2 (s) to R1 (NS).

Install a 47 K resistor (yellow-violet-orange) irom J1 (NS) to J2 (S).

Install another 47 K resistor from H1 (NS) to H2 (S).

Install a .1 of capacitor between H3 (NS) and D2 (NS). Position this capacitor as shown in
the pictorial and cover the lead going to D2 with a 1" length of insulated sleeving.

Connect a 1 megohm 5% resistor (brown-black-green-gold) between H3 (S) and D6 (S). Use
a 3/ length of sleeving on the lead to D6 and position as shown.

Connect a 1 megohm 5% resistor (brown-black-green-gold) between H1 (NS) and D2 (NS)

(use sleeving on the lead to D2).

Install a 1 K resistor (brown-black-red) between H1 (S) and D3 (S) (use 1/2" of sleeving on
the lead to D3).

Connect a 22 K resistor from J1 (NS) to E2 (NS) (use 3/8" of sleeving on the lead to E2).
