Safety

 * As always when dealing with electricity, use caution when dealing with large amounts of current and voltage, making sure not to touch any exposed metal especially when inserting and removing banana clips.


 * Consistently check the temperature of the capacitors as the AC transformer can easily overload the capacitors and burn them out or if the capacitors are connected in reverse they can easily be damaged.
