I have a question that I'm hoping you folks can answer. I'm working on the summer maintenance of our venue's Source 4s and I'm finding a I'm having a problem with some of my 36 degrees. They are showing what appears to be the clips holding the
lens into the barrel around the edges and/or has a bad corona effect. When I endeavor to align them they only go away sometimes- even if I get the spot right in the center and it is perfectly flattened (or so it seems- it could be I'm not getting it right on the money I guess). I've checked the barrels but that does not appear to be the problem so I am guessing it is in the lamp socket or the
reflector. Can anyone offer my some insight on this?
