Did you try the D-76 diluted 1:1? I've gotten very good results with APX 100 - at least for a condenser enlarger - with D-76 1:1, but at less time than the standard recommendations: 9 minutes at 68 degrees with agitation at 1-minute intervals. (The times I've usually seen listed for this film/dev combo - 12 minutes, I think - would definitely overdevelop and wreck havoc with the contrast and grain.)(posted 9116 days ago)
