I remember the big, old B&W TV's at the houses of my elderly relatives.
They were particularly bad for me because, as a child, I could
apparently hear well into the 20-40KHz audio range. This means that I
could *hear* some of the circuitry in an operating television (I presume
the flyback transformer). Good if you are a 6 year old looking for
video games at Kmart, Sears, etc.; bad if you are a 6 year old watching
television on an ancient TV.
15750 Hz. Horizontal output frequency for B&W TV. Well, actually
15750 cps since it predates the adoption of Hz as a frequency unit.
Nowadays 15734.26573 Hz for NTSC color TV.
