If you act quickly, you might still be able to pick up a couple.
My tongue is now plugged in!
Having long been addicted to replenished D23, I tried D25 several times but it was just too soft, and mushy for my taste. Kodak does suggest using half the bisulphite; but I never tried it. D25's replenisher, DK-25R, however, is what I use to replenish my D23.
The formula I posted shows bisulphite, while a Kodak formulary that I have shows metabisulphite. Kodak also suggest that D-25 is used at 25*C (77*F) and to use the development times for undiluted Microdol-X for 20*C (68*F).
I don`t want to make it, I was simply curious how it performs with modern B&W films, hence my question if anyone has used it.
Sorry Ron, but I don`t see the connection between D-23, D-25 and Rodinal.
Bisulphite is mainly Metabisulphite, US ambiguity.
Kodak in Europe seem to have had to adjust between the mixed Bisulphite/Metabisuphite sold as Bisulphite in the US and the pure Metabisulphite sold in Europe, it may really be differences in manufacture.
I only mentioned from your OP, Rodinal and Patrick Gainers attempts at a Metol equivalent.
These are sulfite developers with alkali and Metol. They represent the gamut of what can be achieved by this combination by varying basically 3 ingredients to optimize for either 2 of the 3 properties we want from a film. Vary the pH to a higher value and you approach Rodinal or Patricks formula and etc, especially if you use it very dilute as Rodinal is. Ian caught my analogy right off in another post. No need to repeat it here.
My bottom line is that with a few basic ingredients and a small set of experiments you can play with the developer and get it to do most anything you want. When you add other, more exotic ingredients, a point I have made elsewhere, you push outside this "triangle" and can get some vastly improved properties.
