...Anyway, then the story gets messy. I got a very thin couple of negs from the first mix. I talked to John Wimberley ( we were corresponding already re. the Durst 138S ) for de-bugging ideas and then got a pH meter and tested the B solution, then the full developer mix, both were too low, not alkaline enough.
I concluded that there was either an error in the sodium carbonate that I'd been sold, or I had mixed the wrong dilution somehow.
I then bought some more carbonate from EBay.
I mixed this (carefully ) and tried this. The negs were still thin, but better, and with a light stain.
I then tried 1+1+50 and got a further improvement but it was still short of a few that I'd developed in PMK, both in density and stain in the upper values.
Then it got to the point I was wasting too many sheets, and had real subjects to take, so I cut losses and mixed up more PMK from the stocks I had.
However tthe WD2H A and B are still there, waiting for me to figure out what to try next.
I would appreciate someone else having a go !
John was struggling to remember enough to advise, given that he doesn't have all of the notes from 25+ years ago when he did the last reformulation.
