Well I thought I had better update my progress or lack of progress. I found a source for a replacement fan and was able to install it with little difficulty. It is almost an exact duplicate of the fan that was in the original Ilford head. So I was hopeful until I got it onto my enlarger and it didn't make a difference in the vibration. After having several darkroom friends look at it we agreed that it must be effecting the sharpness as the vibration is significant. The only answer I can come up with is to remove the fan and hook up an external fan system. At this point I am thinking about how to do that.
