The instructions are outdated.  It's a minor issue, but not one that'll stop a seasoned electronics vet, but a noobie might trip up on it.  It has a few capacitors with higher voltage ratings than the instructions list.  For me or anyone not new to electronics, you can use the power of deduction and some common sense to figure out where they go.  No biggie.  Could cast doubt for a complete noobie who's just getting into electronics.  But like I said, minor issue.
