I'm tussling a bit with Foma, but several variables are involved, so it will be a few weekends of working to figure them out. Others report no difficulty.
You probably know that the principal difference between results from condenser and diffusion sources is a higher contrast from silver negs with condensers, all other things being equal, due to the Callier effect. With smaller formats, in which grain is apparent in the print, grain is also emphasized. some who have tested both enlarger types side by side say that equalizing contrast is simply a matter of adjustment in film development and/or paper grade.
I hope this helps.
