Interesting regarding safelight and the Emaks....I read about the red safeligh only warning, and for a good many prints I used just red. However, as I like to develop to completion, I found that using on the red safe light made observation of the black tones a bit tough. Thus, I took out a sheet of Emaks, turned on the usual OC that I use for Ilford MG, and after a few minutes, developed the sheet. To my pleasure, I noted no fog. For succeeding prints I used BOTH the red and the OC safelights....no evidence at all of any fog on any of the prints. My OC light is in the ceiling, probably about 5-6 feet away from the enlarger easel; perhaps I was lucky without knowing why. I have NOT tried the OC light with the Slavich, but I think I will do an experiment with one sheet just to see if there is any effect. Of course, I have noted the warnings regarding red safe light only with Slavich as well.
