Sorry for such a late reply! but Hi there I am a TV/computer collector, I have a 14" National Quintrix TV from 1983 which I still frequently use and made right here in NZ too. I am in Wellington, It is a shame as I had to chuck out 3 80's woodgrain sets including a Pye vid-matic and a Philips a few months ago due to no room! but I kept this National as it has a UHF/VHF tuner and my set top box has UHF out, I know a guy who works at a recycling centre who may be able to give you one whether it be a 1970's or 80's console TV or a portable he should have one. and yes I tell him to keep an eye out for any vintage computers that he finds!
