@Mordacai , no luck for me either. I did see the end of gold plated screw when I lifted out the airflow control screw on the positive post. Looks like the head of that is on the bottom of the hovering deck.
It seems it's screwed down. I put a screwdriver in the airhole, banged it with a hammer and it came a little looser. But still not enough space to lift out that negative post. Tried everything, even sticking a metal rod down the hole of the centerpin in the bottom and trying to hammer out the negative post by force.
The atomiser is in remarkable shape after all that, but it's still going in the bin. Just done harvesting the o-rings and screws for that "you never know when" baggie
