'Cept that don't work with a Beseler condenser head. The Beseler moves the negative stage up and down the cone of light until it just covers the negative area. The enlarger works pretty well if you have the neg higher up than optimum but you lose some light intensity, if the neg is to lower it won't have enough coverage.
