hello, i have a nice working sony tfm 1000w for i think from 1968, it has the best fm audio i have heard, with its quality oval speaker, its uses 4 d batteries, and a dc input, if your going to use the dc input take out the batteries first,its in good working condition,there is a very small missing piece as shown in pictures it tunes very nice and has excellent audio. the dial light works, from a non smoking home.
