Here's the anecdotal story I heard about the "Man Man Muntz" design
technique.

Muntz would commission a TV design, from professional TV engineers, since he
was admittedly not a circuit designer. He would then attack the working
prototype, removing one part at a time. If the TV still worked, he would
remove another part. If he killed it, the part went back in, and he tried
another part. Eventually, he was down to a low parts count. (Well, if it
isn't true, it ought to be!)

This resulted in a drifty, low sensitivity, noisy TV. But in those days,
there were only a couple of VHF stations in any metro area. And the
receivers were used within 10 miles or so of the transmitters. For their
time, they were OK. But as people moved out to the suburbs, and more
channels were used in a region, Muntz receivers began to show their
problems.

I try to get designers to emulate the Muntz technique for EMI control. It's
a lot easier to have more EMI control components in your design, and remove
a few of them during testing, than it is to have to add control components
to your device.

BTW, I remember that, in the mid 50's in Chicago, Muntz was really big on
using skywriting advertising!
