Thanks again, Tom for another magical gadget. This is the Sony KV-4000, a color tv that sold around 1981 for US$550. Sony’s products are known for incredible performance in a small package and this is no exception. The screen measures 3.7″ diagonally, and the chassis measures 4 3/4″ x 4 3/4″ x 11″! The pedestal also serves as a tuner and could by powered by AC, DC or battery power. Tom stole this on eBay for $60. Of course it wasn’t working, but it took him all of 10 minutes to fix it. Thanks Tom!
