something like this will NEVER work on vintage TVs I have tried, they are JUNK
you will get NO color or barber pole effect due to the sloppy colorburst it puts out, solid state TVs work MOST of the time, but tube, NEVER will.
you must have a Cable box that outputs composite video (ntsc) for it to work correctly

+1. I've had mixed luck with those. I've had that same box with a couple different brands on it. First one worked great for a few months (of occasional use) then lost video completely, the replacement would get and loose color randomly and have other issues.

I've got an older metal box HDMI to AV adapter that's out of production that works better. Though my go-to is an HDMI to ATSC transmitter and a DTV converter box for my tube sets...It's expensive but gives me the best quality and aspect ratio control I've been able to get from HDMI sources.
This video gives an overview of that stuff. https://m.youtube.com/watch?v=hKjt3x4WtWU
