1.Selection of rectifier 6A10 (6A) rectifier, common market power, mostly use 5404 (3A) rectifier, rectifier strong load capacity, and little heat and stable performance.
2.Use BU406 transistor regulator, the common market compared to 7812 (or dual 7812) triode regulator to stabilize and BU406 theoretical maximum output current of 7A, 7812 only the theoretical maximum output current of 1.5A.
3.Fiberglass circuit board material using double-sided, common market power and most are single use cardboard panels, glass fiber board from going much stronger than cardboard texture, combined with a double panel, after such elements tin Weld, poor contact and so greatly reduced, and the internal circuit easily damaged.
4.Plus a large heat sink, cooling effect is better; if you use the power in the south, in hot weather, the heat is not good if it will speed up the aging rate power, shorten life.
