That is a good enlarger. Maybe you are doing something wrong. What exactly won't' 'align'
Quote from Modern Photography 1977:
I can't get the lens to be parallel with the negative stage. And if I somehow get close, I then discover that it goes out of alignment when I raise or lower the lens. The tilt of the lens is set by three set screws behind the bellows, which proved to be more like a torture device than anything useful.
