Do not dilute for use.
Process for 6 min's at 20c. Agitation for first 30 seconds then 15 sec's every minute on the minute. To adjust the contrast use greater or lesser amounts of Hypo. Use of more will result in a softer image, less increases contrast.
I have not tried this myself but saved this formulae because I'm dying to give it a try sometime. Have fun!
John, with one exception, this is Grant Haist's Monobath MM-1 formulation. The exception is the addition of 8ml of a 25% solution of Gluteraldehyde. Haist states that this formulation will produce identical results to D-76 when processing Verichrome Pan.

Note: In this formulation, sodium thiosulfate (pentahydrate) is 110 grams. Sodium thiosulfate (anhydrous) is 70 grams.
