Connect a choke (10 mh) from pin 4, V1 to pin 3, V2 (S3).

Connect a CC.1 (brown, black. grey) from pin 2. T2 (82) to pin 4, T2 (82). Position this
capacitor so that it does not block the hole in the bottom of the transformer can (the

alignment hole).

Connect a 220 ohm resistor (red, red, brown) from pin 7, V2 (82) to L3.

Connect a CC .001 from pin 4, S5 to L3 (S4).

Connect a CC ,001 from pin 2, 56 to ground lug A, SS (SI).

Connect a 47 K resistor (yellow, purple, orange) from pin 2, SE to pin 4, S5 (S3).

Slide 3 1 piece of black insulation material (spaghetti) over the end of a CPM .l with the
black band, and connect this end to pin 1, V3, (S3). Connect the other end to pin 1, S2.

Connect a CC '22 (red, red, grey) from pin 2, T3 (82) to pin 4, T3 (82). Position this
capacitor so it does not block the large hole in the bottom of the transformer can (alignment

hole).

(Check all wires. connections, and soldered joints before continuing. Make sure your layout
looks exactly like the diagram above.)
