Orient the transistors so the position of the metal tab matches the silk-screen outline.
Solder the outside leads first and assure that the transistors are straight, then solder the
center lead. Let the shoulders of the transistors leads set their height above the board

Q6
TIP32C
Inspect your work for the absence of solder bridges when you're done.
Install the Capacitors
Install the polarized electrolytic capacitors. Note that + sign on the silk-screen shows
where the positive side of the capacitor should go. However, the markings on the caps
prominently show the negative side. Make sure that the non-negative side of the cap
connects to the hole indicated by the positive sign on the silk screen.

You'll notice that the edge of Q6's heatsink may be rather close to the anode of D9. This isn't a problem
as D9's anode connects to Q6's collector.
