Install the non-polar Capacitors

These capacitors are not polarized, so it doesn't matter which way they are installed on
the printed circuits.
Designation Value
C5 0.1 µF
C6 0.1 µF
C9 0.1 µF
C10 0.1 µF
C7 0.01 µF
C11 0.01 µF
C8 0.033µF

Install the Polarized Electrolytic Capacitors

These capacitors have a polarity. If you put them in backwards:
 The power supply won't work
 The capacitors may explode sending their insides racing to the outside
Please re-read the above sentence, and double check the capacitor polarity before you
solder them in place!
Please double check the polarity of each capacitor upon installation
Designation Value
C12 47 µF
C13 47 µF
C14 47 µF
C15 47 µF
C1 2200 µF
C2 2200 µF
C3 2200 µF
C4 2200 µF

Install the TO-220 Regulators and Heatsinks

There are two regulators, both in TO-220 packages. Be warned...they are different, and
they are not interchangeable. Make sure you double check your work before you solder
them in place.
1. Start with U$1, the µA7815. Spread a thin film of heatsink compound on the back
of the regulator, see Figure 4.
