Now I feel better. That is what I thought I was doing, although I agree that 0.05 moles of p-aminophenol is probably not a relatively small amount for a working solution considering that Rodinal has less than 1/5 that much in a 1+50 working solution. The pH of Rodinal is quite high, while my experimental stuff is between 9 and 10, probably that of a borax solution.

I should test to see how little I can use.
