I had some p-aminophenol from P. F. and tried 1/2 tablespoon of that with a tablespoon each of sulfite and carbonate in a liter for a quickie. It needed to be diluted 1:1 to resemble the potency of working strength Dektol. A print from 35 mm on Arista VC FB showed good tones, but I have no AZO to test it on.

This was the plain p-aminophanol, no HCl. The p-aminophenol HCl I had in stock (no wonder Kodak calle it Kodelon) had turned so black that I couldn't see a print thorugh a half inch of it
