Ok, this is a question.
You have 1 7809 v regulator and 1 7812 (12v for 6581) by using the jumper you choose.
You always should measure your voltage after soldering your pcb (and test the jumper), so than you are save.
However, I recommend using a SwinSID if you are a Beginner or want to be on the really save side and protect your SIDs as long as you are in the soldering/building/testing progress. And care about the advice I gave you about 6581, they are old, they are rare. It's better to use just 2 or 1 instead of them all because they are old and rare and they are kind of fragile now.
