It's good practice to keep the bottom heatsink straight so that it doesn't touch the near-by

trace. It's actually not a problem if it does touch it, since the two nets are connected

Figure 7).

Install the Small Non-polar Capacitors

Designation Description

0.01 µF, 400 Volt film capacitor, box capacitor

Install Shunt Regulator and Small Transistor

Be very careful. The shunt regulator and small transistor come in the same type of

package, known as a TO-92. They sit right next to each other on the PCB. However,

their functions are very different. Make sure to read the writing on the packages to get

the right device in the right place.
