- Argggh! Ok, fine. I think we've found the root of our little disagreement
- here. I really do hope that most people interpret "DC" to mean "stuff that

- Yesss... But back to blankets, having, say, 5V of ripple on 177V DC is
- going to produce a proportionatly smaller field that plain old 120V AC.
