    From what I've read, the Tetanal C-41 kit is a blix kit. Is it possible to use it as separate bleach and fix baths?

    You can use the dark red part as bleach if you add lots of Bromide, e.g. 50 g/l Ammonium Bromide. The second part, a yellowish liquid can be used alone to make fixer.

    So it's not as simple as one part being a standalone bleach, and the other being standalone fixer. B is a standalone fixer, but A depends on B to work?

    Since I haven't been able to find the Fuji kit Stateside, what's the best way (short of mixing bulk chemistry) to do a non-blix C-41 process in small quantity?

    Part A converts Silver to Silver ions, and Part B forms a soluble complex with Silver Ions. If you leave out Part B, you need an anion to make the Silver ions happy, preferably one the Silver ions really like, e.g. Bromide.

    I have seen a report where someone just tried to mix Part A and Part B into separate bathes and he got brown stain on his slides - an indication that Silver was left behind.

    Thanks for the link! I hadn't run across that thread before. I'll read through it . . .
