Ammonium Ferric EDTA solution (50 - 60%) 200 ml
Ammonium Bromide 150 g
Disodium EDTA 10 g
Ammonium Sulfite 10 g

Thanks for the formula! JD Photochem has the Ammonium Ferric EDTA solution (50%) for $19 a liter, Ammonium Bromide for $10 a lbs., Disodium EDTA for $15 a pound, and they don't carry ammonium sulfite. So roughly this mixture is $4 a liter plus shipping. I think that I paid $9/L plus shipping for the Kodak product. Maybe some of the chemicals can be found for less.

Kodak says to use all the solutions one-shot in a Jobo. Is this really true from the bleach and fixer?
