Now you’ll install the non-polarized capacitors. We start with the smallest capacitors, and
work toward the larger capacitor values. These capacitors are not orientation sensitive.

The following capacitors are electrolytic capacitors.
The polarity is important. Be sure to
look at the polarity as marked on the silk screen, and make it agree with the capacitor
markings.
Note that the 47 µF capacitor foot print doesn’t quite match the PCB, but it
installs reasonably well.

Match the shape of the transistor body to the shape of the silk-screen. Leave about 3/8” of
space between the bottom of the transistor package and the PCB. Don’t get too much heat
onto the transistors.
