I am finally building my darkroom and have a Devere 504 with the Dichromat head and the universal timer. In a few weeks I'll be able to actually use it rather then just stare at it!! I would like to print using a metronome hooked up to a foot switch rather then use the universal timer. Something like the metronome compensating timer from Zone VI. Has anyone configured something like this on a Devere 504 or similar enlarger and if yes, what did you use and how is it hooked up? Or any suggestions on what might work? Thanks in advance for any suggestions!
