There are still many high-tech products which fit in this general
description. Adjusting tunable filters, Focusing TWTs using permanent
magnets, etc.
at lunch today, someone was talking about a guy from RS Microwave
commenting that they had fooled with automatic filter tuning by
computer, but a "good" tech could beat it every time. the machine tuning
worked great for a specific filter, so if you had a big production run,
it was ok, but if you're building just a few of each filter.
