You do realize the color killers function is to look for the color burst in the recieved sync signal and turn the color off if there is no color burst in the recieved program, right?

There's basically nothing out there designed to send monochrome programming without a burst running* so the killer should naturally be in the color circuit enable state all the time.

* Some people with monochrome TVs will chop up a cable so they can take the luminance coax from the S-video output of a device and use that for burstless high resolution monochrome, but it seems pointless to do for a color set.
