For those who have experienced or are concerned about suffering Xtol failure, I strongly suggest you give Ilfosol-S a try. It's a phenidone-ascorbate liquid concentrate, easy to mix, seems to be readily available, and has consistently provided me with results comparable to good batches of Xtol. I've used Ilfosol-S 1:14 at 75 degrees with 120 TMX on a Jobo CPE-2+. I've no connection with Kodak, Ilford or any other photo industry entity; just a happy camper who finally found the combination to stick with.(posted 8418 days ago)
