I'll have to pay closer attention next time - thanks for the info. i made an interesteing discovery last month when I accidentally processed some Techpan in some split D23. The results were quite good. Still probably N+1 or more but very printable - good film speed - nice Tech-pan grain structure. In case you don't know the brew it is

Part A
1 Liter water
85 g Sodium Sulfite
6.25 g Metol

Part B
1 Liter water
12 g Sodium Metaborate

4 minutes in A and 4 in B - nearly any emulsion, standard agitation, wide temperature tolerance - no wash between stages - does about a dozen rolls of film for less than $3.

You can get the chems for photoformulary.com
