[QUOTE=analogfotog;621050]I am trying to compound a developer which has slightly more contrast and slightly less density than the modified AGFA-Ansco 17M

It seems to me you are creating a problem then looking for a solution. Instead of Ansco 17m, just use D76. Would not the additional hydroquinone in D76--compared to Ansco 17m-- do exactly what you want?-Moreover, the old lab rats with whom I worked back in the 1960s would sometimes increas the borax concentration of D-76--even substituting Kodalk, sometimes.
