I apologize for the lack of apparent progress in the electro-archaeology of Hilgen amplifiers. However, the materials I received from Jack Gentul's family are so numerous and varied that it has been difficult to formulate a way of presenting them coherently. In addition, many a document that at first appeared unremarkable has turned out to contain important details about what I thought I understood about Hilgen or clues to parts of the story that I had never anticipated. At times my options seemed to be either to (a) start the site all over again or (b) give up completely. I know realize that I must follow the maxim that seemed to guide Jack Gentul's work over the course of four decades:
"do the very best you can with whatever is at your disposal. It doesn't have to be perfect. Nothing is routine; experiments are the norm."
So, what were we discussing before I was so fortunately interrupted?
