Excellent enlarger! I have two of the G70s One with the integrated color analyzer , one without and a Unicolor branded third. And YES!!!! I have the Manuals for them!!!! There is NO heat from the lamp. The condenser/diffuser block effectively eliminates this. It will easy to build a full frame carrier from a few layers of cardboard paper and a peice of microglass, But keep your carriers intact. Like others have said, they can not be easily replaced.
