I spoke for about an hour this afternoon with Fred Zonfrilli, elder son of Joe Zonfrilli, one of the founders of Sano Amps. Fred, at 75 years old, is a prince of a man. Many thanks to the ever-generous and humblingly-talented Larry John McNally for helping me make this connection.

I need to correct some of my information about Jack Gentul, but the timeline is starting to make sense. One really significant piece of information for now: Jack Gentul designed all but the earliest of the Sano tube amp circuits, and ran the manufacturing side of Sano for just over a decade. So Jack is not only the fountainhead of Hilgen amps, but Sano amps as well.
Not a bad track record.
Will revise Jack Gentul page tomorrow with new information.
