The 15V/30V version, the L01-6383 will be better for 12V. It's preferable/required to use Low ESR electrolytic capacitors. The large caps can be 3900uF to 4700uF. It is HIGHLY recommended to use a Corcom/TE power inlet module with this PCB. In fact, the mains/primary side is labeled to match these inlets for ease of building. Use the TE PS0SXDBX0 (or equivalent module). The heatsinks that fit this PCB are the Assmann WSW Components - V8813X. These are 1.5" tall to match the rest of the components. The dissipate plenty of heat, however there are 2" tall models as well that can do even more. If you have the room, I recommend using the taller ones. The Littlefuse V250LA20AP MOVs are what I use on these boards. There are quite a few similarly specced ones though that will work just fine. Just make sure they match the voltage requirements, and board footprint. I recommend the Bourns 3362 (flat style) trimmers (with the triagular pin arrangement)
