I remember as a kid thinking that the spring sound of the volume control power switch was what caused the bouncing collapse of the raster on our Admiral bakelite console TV set. THe horiz would shrink some while the vertical held steady, then the vertical would decrease while the horiz was steady, and so on, Then one time the power failed while we were watching TV on it, the raster collapsed as usual, but without the switch spring sound...
