More confusion....

Looking at Kodak J-39 publication, it seems Kodak makes/made two different kind of RA chemicals. One that becomes Developer and Bleach-Fix and another that becomes Developer Replenisher RT and Bleach-Fix Replenisher. I can tell these are different chemicals because mixing instructions are different. Later also involves a starter.

Looking at Adorama and B&H, it appears the latter is the only available choice. I can buy them in 10 liter bundles.

I will likely use these as one shot, not replenish.

Am I assuming correctly that I CAN use these for one shot? What about starter? Do I need to add starter every time?

At this point, I'm thinking I'll either do tray or tube processing. (unless I go completely NUTS and buy a mini-lab... kidding!)

I'm quite confused.
