Add RCA Component Sound And Video Hook Ups

[damen]

Just curious if anyone has had any luck trying to add a component video and sound hook up to a tube TV set like ctc 15,28,38 or other. I know this was afford for ctc 38 sets for special models think there called Lyceum which I have not been able to find a schematic for probably cause of there rarity. I am thinking about trying to do this but want to see if anyone else has or may have a schematic for a tube set that had this option.
