Still, it's interesting that the atlasnova were predrilled. Both of mine were in the 10-14mw range. So if they were factory drilled to ensure <5mw, someone was asleep at the wheel. And I do believe that Arnold does not modify his. But turning the pot on his gave me no more power. Oh, wait, you said they do it to make sure that they were not over 20mw. I guess that does make sense. Can anyone say if the Atlasnova high spec units (>30mw)are predrilled?
