I wonder just how available were the delay lines needed when NTSC was
introduced? They were quite an expensive component years later.


NTSC delay lines for TV sets were about $3 for replacments in the mid
'60s. I only saw one open delay line and one with physical damage in
40+ years. The open delay line removed the luminanve signal, leaving
only moving colored splotches on a black screen.
