might try putting the 2nd element on at 25% to see what happens
When i first built my bubbler i had trouble with a dropping Abv through a run, much like a pot still.
In the end it came down to not quite enough reflux and in part running it outside in the cold night air. Too much heat was getting lost. Needed more heat.
Now i run a 2400w element flat out and the other partially on with a volt controller.
Perhaps your element isnt doing you any favours here either?
Hey Dans.brew :text-+1:
Thats also been the train of thought as the element has lost 200 watts in punch, so might try the 2nd element at 25%. Just need to change one thing at a time otherwise you loose track of what the final result is. Couple of things to work on. Can't do much else until "Dan" opens up Victoria.

Guess what. Looking at my notes. I see I put the 2nd element on when collecting the heads. (Yesterdays Run) Only at 25% and my ABV went from 85% to 90% it stayed at 90% until the tails came
So it is a heating issue.. More heat more reflux ratio and more ABV. Haven't in the past had to use the 2nd element on the heads etc. I think problem solved.
Good stuff... classic insight into how important note taking is in this hobby, especially if your looking for that superior spirit... all the little bits add up. :handgestures-thumbupleft:
You'll notice a bit of a jump in the flow down your downcommers now, i did.. all the stuff going down was what was more than likely holding your Abv down.
