I have just purchased a used beseler mcrx with a dichro dg head. everything appears clean and in good working order. There is a part to it though that is confusing to me. There is this separate piece that is a box that is to be connected to the actual enlarger head by a hose. Being new to all this (having my own equipment...) I am wondering what is the purpose of this unit. Is it a necessity, etc.
