PC-TEA is a winner of a developer, though, and seems to have declined in popularity here as compared to a couple of years ago. We need a new round of people taking it up. It's only slightly more complicated than D-23: (P)henidone 0.225 g, vitamin (C) 9 g, and (T)ri(E)ethanol(A)mine 100 ml. You need to heat up the TEA for the ascorbic acid to dissolve; I use a baby-bottle warmer (retired from its original use!). Use at 1+50, with starting dev times the same as for Xtol 1+2.
