    Thanks for the info - I acquired some chemicals where the developer was shot.

    I've had some success with Dektol 1:1 and ~1/4 tsp hypo/liter. The print is a bit duller than I'd expect, but that may be due to me trying a new process :-) Difficult for me to tell what is my fault, the fault of older paper and what is the fault of the developer mix. As noted above, dektol without the hypo introduces a yellow shift I found hard to correct for. I'll be doing more extensive testing in the upcoming months.

    Sorry I didn't see this post before - Part B of the developer has a shorter shelf life - it contains the main developing agents, the part A and C of the developer contain mostly modifiers that help tune the chemistry for propere color balance etc.

    Is the sodium thiosulfate pentahydrate or anhydrous form?

    Both can be used, you have just to convert masses; but if they are speaking "about" and "teaspoons", there's not so much difference.

    If they speak about "crystals", then it's probably pentahydrate. To convert it to anhydrous form, divide the mass by 1.57, or if you want to convert anhydrous mass to pentahydrate mass, multiple by 1.57.
