I usually print with my Ilford Multi-grade 400HL and HS VC light sources and like them very much. Now, the reason for the question on the V54 is this. I just bought an Omega D2 with Aristo V54 cold light head and would like to take it to my cottage for printing there. On the Ilford 400 VC print heads there is a control panel with a compensating timer to allow easy changes between paper grades on VC paper. I'm wondering if there was or is a variable VC compensating timer for the Aristo V54 head? I know Zone VI had one, but were there others?
