OK hazz,
heres my best effort on conversion. Basically, just so you know, I've taken the recipe and entered it as an all grain, then taken the percentages of the carapils and wheat, and kept them (but changed the carapils for steep instead of mash), the pils and vienna, just converted to ldme in the same ratio....
hopping I'll leave to you, but you will need to chang slightly due to different processes being followed for extract (ie partial boil instead of reducing boil)
so it is as follows.
LDME 3kg (88.5%)
carapils steeped 65C/20mins 500g (5.7%)
dry wheat extract 160g (5.7%)
23L og 1046
boil: never thought to even ask the size of your brewpot!so, calculate off of the hopping in the original recipe, just scaling the values for your BG and volume, so that you hit the required 26 IBU. (note that tonys volume is, I think 50L. so you would have to scale the hops accordingly....if you have any probs with this, let me know (pref tomorrow, when I'm sober) and I'm happy to help. But let me know the max size you can boil, and the AA of your hops, (if you have them, or when you get them) otherwise its just speculation, anyway.
original recipe is
here
I suppose my next job is to write an article about how to do an AG/extract conversion, cos I notice there isn't one on here.........
Edit....the more I look at tony's recipe, the more I like it......might have to do this one (AG) myself. And I don't even (usually) like american styles. mmmm
