they don’t blow up! The PC board silkscreen will have a “+” marked on it
to indicate the positive lead of the capacitor. The cap is marked with a line
or stripe down one side which indicates the negative lead, which is also
shorter. Be sure the longer, positive lead is placed in the hole marked by
the “+” sign and push the part all the way down before soldering both
leads.
8. Install R3, 470K ohm resistor [yellow-violet-yellow].
9. Install C4, another 10 µF electrolytic capacitor. Again, follow the PC
board silkscreen for proper orientation.
10. Install R13, 100K ohm resistor [brown-black-yellow].
11. Install C1, 390pF disc capacitor [marked 390K or 391].
12. Install R11, the other 1M ohm resistor [brown-black-green].
13. Install C3, 39 pF disc capacitor [marked 39].
14. Install R2, 100K ohms [brown-black-yellow].
15. Install C9, 560pF disc capacitor [marked 561].
16. Install C10, 1800pF disc capacitor [marked 182].
17. Install R7, 75K ohm resistor [violet-green-orange].
18. Install R6, 39K ohm resistor [orange-white-orange].
19. Install R8, 100K ohm resistor [brown-black-yellow].
20. Install C18, 3900pF disc capacitor [marked 392].
21. Install C19, 56pF disc capacitor [marked 56].
22. Install C5, .01 µF disc capacitor [marked .01 or 103 or 10 nF].
23. Install R10, 47K ohm resistor [yellow-violet-orange].
24. Install R9, 100K ohms [brown-black-yellow].
25. Install R12, 47K ohm resistor [yellow-violet-orange].
26. Install C12, 10 µF electrolytic capacitor. Remember to watch the
polarity!
27. Install VR1, the 78L05 voltage regulator [marked 78L05]. You’ll note
that there is a flat side to this part that will help you correctly place the part
into the board. Gently bend the leads before installing. This part must be
installed in the proper direction to work so follow the PC board silkscreen
for proper orientation. Solder all three leads.
28. Install C15, .1 µF disc capacitor [marked .1 or 104].
29. Install C14, .001 µF disc capacitor [marked .001, 102 or 1nF].
