Step 1
– When installing components, insert no more than 1/8” of lead
into the terminal holes. Trim all excess beyond this 1/8”.
Step 2
– From the right side of the board (photo 6.9a), install a 47ufd /
50V cap across terminals T3 and T4. Make sure the positive terminal
of this capacitor is connected to T3. Solder component into place.
Step 3
– Install a 825Ω resistor between turrets T1 and T2. Solder in
place at both terminals.
Step 4
– Install a 100KΩ resistor between turrets T7 and T8, soldering
at both terminals.
Step 5
– Install a .0047μfd Mallory capacitor between turrets T9 and
T10, soldering into place at both terminals.
Step 6
– Install a .01μfd Mallory capacitor between turrets T11 and
T12; solder at T12.
Step 7
– Install a .01uF capacitors between turrets T13 and T14;
Solder at T14.
Step 8
– Install a .022μfd Mallory capacitor between turrets T19 and
T18; solder at T18.
Step 9
– Install a 470KΩ resistor between turrets T13 and T17; solder
at T13.
Step 10
– Install an 825Ω resistor between turret T15 and T17. Solder
at T15.
Step 11
– Install a 470KΩ resistor between turrets T19 and T17.
Solder at T19.
Step 12
– Install a 47.5KΩ resistor between turrets T16 and T17.
Create a small loop at the lead end that goes to turret T17 and hook
around the inserted lead of the 825Ω resistor (photo 6.9b). Solder at
both terminals.
Step 13
– Install a 68.1KΩ resistor between turrets T20 and T21.
Solder at T20.
Step 14
– Install a 68.1KΩ resistor between turrets T22 and T21.
Solder at both turrets.
Step 15
– Install a .0047μfd Mallory capacitor between turrets T23 and
T24. Solder at T23.
Step 16
– Install a .0047μfd Mallory capacitor between turrets T25 and
T24, Solder at T25.
Step 17
– Install a 47μfd/50V Electrolytic capacitor between turret T27
and T26. Make sure that the positive of this cap is soldered to T27.
Step 18
– Install a 475KΩ resistor between turret T24 and T26 (photo
6.9c). Solder at both turrets.
Step 19
– Install an 8.25KΩ resistor between turret T27 and T28. Solder at T27.
Step 20
– Install a 2.2MΩ resistor between turret T28 and T29. Solder at T28.
Step 21
– Install a 475KΩ resistor between turret T30 and T31. Solder at T30.

Capacitor value descriptions uF and uFd are the same. Also, the values for the brown
radial leaded capacitors are written on the side in code. Refer to page 62 on reading this
