For your consideration is a 1976 Panasonic TR-739 portable B&W 9" Television. Solid state
3-way sure power can run on batteries, wall outlet, and has 12V lighter
plug input (cable for car cord and batteries not included). Powers on and shows a static so it appears to work as it should, but I don't have a digital antenna converter or any other way to test this further than just powering it on.
This is in pre-owned vintage condition with appropriate wear from age, use, and storage. Please use zoom function and see pictures for additional details and to make your own judgments on condition.
