Here's the first TV I remember, b&w of course. It was a Muntz. It was said old man Muntz would wander the lab looking over the shoulder of engineers developing circuits. Then he'd pull wire cutters out of a pocket and start snipping components out until the circuit failed The idea being building the cheapest set on the sales floor with a decent picture in strong signal areas (where the bulk of the customers are) that would last a few years until a new model came out. The practice of getting circuit component count to the bare minimum became known as "Muntzing." The red X in the picture is where you kick an old set when the horizontal hold looses lock. (Wonder how Dad discovered that?
Was my first lesson in consumer electronics repair.) And jiggle the tuner knob if the picture goes snowy. Try doing that with your new digital box And the old Muntz wasn't a threat to spy on you.
