Ah thank youy Bob, that's perfect, even more so since B is cheaper ;)

They both work. "B" is said to give longer lifetime to the developer.

Phenidone A or B?

Greetings,

Could anyone confirm the type of Phenidone that is to be used in SM-6 developer, is it type A or B (Methyl-Phenidone) as the more sources I check the less I know... there seems to be a lot of discrepencies out there on the exact formulaes. Unless both are ok to use?

Same question stands for the Quephe and the RCA developers.

Thank you
Loic
