Response to The Trouble With Xtol

I used Xtol without any trouble from the 5 liter packs, stored it in one 2.5 l plus two 1 l glass bottles, there actual volume was very close to 5 l. First I used up the two small bottles and then splitted the big one in into the small bottle, using the left over developer right away. Used it 1:1 or 1:2 in small tanks or 1:1 in Jobo CPE, with a minimum volume of 80 ml straight Xtol per film.

Than I changed to Mytol, a formula similar to Xtol which I found on the page of Mr.Jones (www.jetcity.com/~mrjones/index). BUT I changed the formula for the Na-ascorbate to using 2 parts vitamine C and 1 part NaHCO3, as I think the original formula is not correct.

Modified to my stock chemicals for 2.5 liters:

0.375g Phenidone 29 g Vitamine C 14 g NaHCO3

150 g Na2SO3 7.5g NaHSO3 7.5g Boric acid 5 g NaOH

The later substitute the Na-metaborate I do not have in stock. So problems so far and I can mix any quantity I need. Downside I can not blame Kodak for any trouble. For the Jobo CPE I'm using the small tank times -15% as a guide line, as the Xtol times for rotation gave too low contrast.
